Aims and Objectives Introduction: In this coursework, I will be conducting an experiment, to show a particular factor affects the rates of a chemical reaction. The main factors include concentration/pressure of the reactants, presence of catalysts, particle size and temperature. I have chosen the effect of temperature on a chemical rate of reaction. Aims: The aim of this investigation is to find out the effect of Temperature of the acid, in the reaction between dilute hydrochloric acid and magnesium ribbon. This reaction is a single displacement reaction, which is when one of the atoms' formulas is exchanged with another one's, like A + BC è AC + B The rate of a chemical reaction is a measure of how fast the reaction takes place. It is important to remember that a rapid reaction is completed in a short period of time. The following is the equation for this reaction that I will use for this experiment: 2Mg + 2HCl =====è 2MgCl + CO2 I also hope to find a certain pattern; by devising formulas from my results I can compare different temperatures and their rates of reaction among each other, which should suit my prediction. Skill Area P :Planning Experimental Procedures Plan: For this coursework I plan to conduct a suitable experiment to show how different temperatures affect the rate of a chemical reaction, from this I hope to aim for precise and reliable results. The following reaction is what will happen in my experiment: 2Mg + 2HCl =====è 2MgCl + CO2 Safety Precautions: In the experiment we will ensure that the following safety precautions are taken: · Safety goggles must be worn at all times during the experiment. · We will need to be aware of your surroundings. When handling chemicals such as hydrochloric acid should be handled with care. Spillages, breakages, of any kind are a danger hazard, must be supervised and reported. · We will need to rid your hands of any traces of chemicals such as
Investigating Rates of Reactions My aim is to investigate what factors affect the rate of reaction between magnesium and hydrochloric acid. The factor that I will be focusing on is the concentration of Hydrochloric acid. [IMAGE]Reaction Equation: Mg (s) +2HCl (aq) = MgCl2 (aq) +H2 (g)
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature-
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 + Calcium Chloride + Water + Carbon dioxide 2HCl (aq) + CaCo3 (s) 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.
reaction is the rate of loss of a reactant or the rate of formation of
The aim of this experiment was to investigate the affect of the use of a catalyst and temperature on the rate of reaction while keeping all the other factors that affect the reaction rate constant.
Throughout the experiment the reaction time of the reactants will be recorded under different temperature environments. The hypothesis of this experiment is that the reaction rate of the reactants will increase as the temperature increases which means that the reaction time would be shorter (faster) as the temperature increases. To justify the accuracy of the hypothesis, the chemical equation of the experiment was examined and studied to predict the products after the chemical reaction; the chemical equation
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
The aim of my investigation is to find out whether the increase of temperature increases the rate of reaction between the two reactants of Sodium Thiosulphate and Hydrochloric acid. I will then find out and evaluate on how temperature affects this particular reaction. Factors There are four main factors, which affect the rate of reaction that are considered as variables for the experiment I will be doing, they are the following: Molecules can only collide when two of them meet together.
In a substance the rate of reaction will be quicker if it has a large
The pH of the solution would alter the rate of the reaction if it was
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.
The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
• Washing hands after touching blood, body fluids, or other contaminated items, even when gloves are worn.
My aim in this piece of work is to see the effect of temperature on the rate of reaction in a solution of hydrochloric acid containing sodium thiosulphate. The word equation for the reaction that will occur in the experiment is: Sodium thiosulphate + hydrochloric acid →, sulphur + sulphur dioxide +. sodium chloride + water ? where the sulphur is an insoluble precipitate.
