Rate of Reaction Between Marble Chips and Hydrochloric Acid The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) takes place. There are many variables that affect the rate of this reaction such as the following: 1. Temperature 2. Concentration (Pressure for gases) 3. Catalyst 4. Surface area In my investigation I will be testing how changing the concentration of the Hydrochloric acid. The aim is to find out if changing the concentration of the hydrochloric acid solution has an effect on the time taken for the reaction. The reaction that will take place is: Hydrochloric acid + Calcium Carbonate à Calcium Chloride + Water + Carbon dioxide 2HCl (aq) + CaCo3 (s) à CaCL2 (aq) + H2O + CO2 (g) Collision theory - Collisions between reactant particles are needed for the reaction to take place in order to form a product. Some collisions are successful and give a product while others don't because particles don't have enough energy. Activation energy - The amount of energy needed for the reaction to be started. If there is enough energy then the reaction takes place and a product is formed, but if there isn't enough then no reaction takes place. There are two possibilities for increasing the rate of reaction: 1. The activation energy is reduced so that there is a better chance of particles having enough energy to react. Reactants will need less energy to react. 2. The number and strength of collisions is increased so that the reaction can happen faster. If the particles have more energy then more particles will be able to react. Solid reactants like marble chips are effected by surface area, the larger the surface area the more collisions that will take place. This will increase the rate of reaction and decrease the time taken. Liquid/ Aqueous reactants rely on collisions for more collisions to take place.
Investigating How the Concentration of Hydrochloric Acid Affects the Speed of the Reaction with Marble Chips
The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.
Investigating the Rate of Reaction Between Marble Chips and Acid Introduction This is a test to demonstrate the reaction rate between marble chips (CaCO) and hydrochloric acid (HCl). Hopefully we will be able to prove that the concentration of the acid is directly proportional to the reaction rate. Aim To discover if the concentration of acid is directly proportional to the rate of reaction, by monitoring the amount of gas given off as the reaction takes place. Prediction We believe that the concentration of the acid will be directly proportional to the rate of reaction. We believe this due to the following theory: [IMAGE]The collision theory: This theory states that for a reaction to occur the reactant particles need to react with sufficient energy.
Text Box: Surface Area When a solid reacts with a liquid or gas, the surface area of the solid particles makes a difference to the speed of the reaction. From the diagram you can see that the three smaller particles have a larger surface area all together (shown as blue) than the larger particle and so will react faster. There are more calcium carbonate particles on the the concentration of the hydrochloric acid
The Effect of Temperature on The Rate Of Reaction Between Magnesium And Hydrochloric Acid Planning I'm planning on investigating how temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed.

Rates of Reaction - Sodium Thiosulphate and Hydrochloric acid In this piece of coursework, I will study how concentration affects the rate of reaction. I will do so by timing the reaction of Sodium Thiosulphate with an acid. In this coursework, I will include background knowledge, prediction, safety, results, calculations, graphs, an analysis, conclusion and an evaluation. In my evaluation I will comment on how reliable my results were and how I could have improved my coursework in any possible way.

The Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Planning. CaCO3 (s) + 2HCl (aq) ---- CaCl2 (aq) + H2O (l) + CO2 The rate of reaction depends on how hard and how often the reacting particles collide with each other. A rate of reaction is how fast a reaction takes place.
from 10cm to 50cm to make it easier to see the difference in a graph.
Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water.

Concentration's Effect on the Speed of Reaction Between Magnesium and Hydrochloric Acid Planning 1: The aim of this investigation is to find out the effect of acid concentration in the reaction between dilute hydrochloric acid and magnesium ribbon. The rate of a chemical reaction is a measure of how fast the reaction takes place. A high concentration of hydrochloric acid could mean a fast reaction whereas as a low concentration could mean a slow long reaction. I will be testing different concentrations of acid reacting with magnesium in two separate experiments, which will hopefully prove this initial prediction. [IMAGE][IMAGE] During my science lesson I have learnt the following information that has enabled me to plan my investigation.
Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
