Chapter 4 | Chemical Kinetics


1. Chemical kinetics is the branch of chemistry that deals with the study of the rates of chemical reactions and their mechanism.

2. Rate of a chemical reaction is the change in molar concentration of the species taking part in the chemical reaction per unit of time. 

3. Instantaneous rate of reaction is the rate of change of concentration of any one of the species involved in the reaction at a particular instant of time. 

4. Order of a chemical reaction is the sum of coefficients of reacting species that are involved in the rate equation for the reaction. 

5. Molecularity of a reaction is the number of the reacting species that collide simultaneously to bring about a chemical reaction.

6. Activation energy is the extra amount of energy that has to be supplied to the reacting species in their normal energy state to make their energy equal to threshold energy.

7. Rate law for any reaction cannot be predicted by merely looking at the balanced chemical equation; i.e., theoretically but must be determined experimentally. 

8. Rate of reaction is affected by some factors like temperature, the concentration of reactants/products, the catalyst, the surface area of the reactants etc. 

9. Activation energy is the extra amount of energy that has to be supplied to the reacting species in their normal energy state to make their energy equal threshold energy.
