...
There are four factors that affect the rate of reaction:
1 - Temperature. ... They will collide more frequently increasing the rate of reaction. ...
Catalyst:
Addition of a catalyst increases the rate of reaction as it reduces the activation energy of the reactants. The catalyst ...

Rates Of Reaction Coursework
What is a reaction? A reaction is when 2 particles (reactants) join to form a new product. ...
What is the rate of a chemical reaction? The rate of a chemical reaction is how fast the reactants react.
For a reaction there must be a successful collision. ... Th...

| 5. | Chemistry Rate of REaction
Aim: To find the effects of the concentration of hydrochloric acid on the rate of reaction on marble chips. ...
Marble chips can dissolve in acids; if the concentration of the acid is varied then the speed of the reaction will either slow down or speed up.
All substances are made out up of parti...

| 6. | Rate of Reaction
Introduction
The rate of a reaction is the speed at which reactants are converted into products. Experiments show that for most reactions, the concentrations of all participants change the most rapidly at the beginning of the reaction. That is, the concentration of the products shows the greatest...

| 7. | Experiment to study the Effect of a catalyst on the rate of reaction
Hypothesis
The Collision Theory says that the role of a catalyst is to provide the reaction with an extra, alternative pathway for the reaction to occur; the activation energy for this alternative pathway is less than the activation energy for the reaction without the catalyst. As a result, more ...

| 8. | Investigate how the concentration of acid used affects the rate of a chemical reaction
Background: The speed of a reaction is known as a reaction rate. There are many factors that may affect the reaction rate, including:
Heat. When heat is introduced the atoms gain more kinetic energy and move at a faster rate and therefore collisions happen more often and more violently. ... Th...
