| 13. | 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...

|
| 15. | 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 ...
