Rate of Reaction Aim: To find out how different concentrations change the rate of reaction Theory: In this experiment the collision theory is in use. It means that when the concentrates solutions of hydrochloric acid is use, more particles are found in the same space, which means they are more likely to collide with each other. the more the concentrated the solution, the more of the collisions with the particles, which increases the rate of reaction. Prediction: As the concentration
Rates of Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to collide with each other in order to react. However, they do not react if they collide without sufficient energy, and therefore the more energy a particle has, the more likely it is to react. The activation energy is the minimum amount of energy
affect the speed of the rate of reaction when reacting with Magnesium Ribbon. I want to find out whether the strength of Hydrochloric acid will affect the speed of the rate of reaction when reacting with Magnesium Ribbon. Variables There are two important independent variables in my investigation the first of which is the concentration of the Hydrochloric Acid used during the investigation. The concentration of the acid will partly determine how fast the reaction takes place, if we put

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) Magnesium + Hydrochloric Acid = Magnesium Chloride + Hydrogen There are several different variables you can such as temperature, concentration; surface area and whether or not to use a catalyst or not
Rates of Reaction Investigation Reactions happen when the reactant particles collide and turn into a product. Sodium and chlorine, when reacted, they give us a compound Sodium Chloride (salt). Chemical reactions can be very difficult to undo. When metal rust this is a slow reaction, however burning, this is very quick. A speed on which the reaction takes place is called and rate of reaction. There are many ways on which to speed up the reaction. The most common is to speed up the collision

Rates of Reaction Experiment INTRODUCTION This experiment is called ‘rates of reaction’, I will be partaking in this experiment to find out what factors effect the ‘rate of reaction’ between magnesium (strips) and hydrochloric acid. Each time I repeat the experiment, I will be adding 0.5 moles of hydrochloric acid and recording the volume of gas given out during the testing and record the time it takes to give the reaction needed. A reaction is taken place within the experiment because there is
Rates of Reaction Experiment Introduction/Aim: This coursework is about the investigation of the effect of concentration on the rate of reaction between Sodium Thiosulphate (Na2S2O3) and Hydrochloric acid (HCL) by simply changing the concentration of Sodium Thiosulphate. I made a set of results which were obtained by using the method of 'precipitation'. This is when the product of the reaction is a precipitate, which clouds the solution. One observes a marker through the solution and
Rates of Reaction Experiment Rate of reaction means the rate of formation of a product/disappearance of a reactant, this is useful because we can time the different concentrations reacting with the acid, and give each of them a rate, based on the formula rate = 1/time. Rate of reaction is what we use to measure how quickly a reaction takes to reach a certain point in the reaction in this case it is when it gets to certain cloudiness. In this investigation, we will need to measure the
Rates of reaction of the halogenoalkanes scientific knowledge and understanding: Halogenoalkanes are classified as either primary, secondary or tertiary. In primary halogenoalkanes the halogen atom is covalently bonded to a carbon atom which is bonded to one other carbon, to two other carbons in secondary and three others in tertiary. Apparatus for a reflux Increasing the size of the halogen atom in the halogenoalkane decreases the bond strength, increasing the reactivity of the molecule

Reaction Rate Investigation Planning I am trying to work out the rate of reaction between marble chips (calcium carbonate) and Hydrochloric acid. This will be my plan of how to carry out my investigation. There are many factors, which I could change in this experiment. These are 1) Concentration. An increase in concentration means there are more particles. More particles means there will be more collisions. 2) Surface Area. Breaking the solid into smaller pieces will increase
Rate of Reaction Investigation Aim: To determine how changing the concentration of a reactant (Na S O ) affects the rate of the reaction. Prediction: I predict that when we increase the concentration, the rate will increase; therefore there are more particles and a greater probability of a collision. If more particles are present in the same volume, they will be closer together. This means they have a higher probability of colliding and speeding up the reaction. If we double
