Question
Ans 1 :
The rate of a chemical reaction are controlled by many factors.
These are :
1. Concentration of reactants :
when the concentration of the reacting species is increased , the number of particles in the reaction increases , which increases the rate of chemical reaction.
2. Surface area of reactants :
Increasing the surface area increases the rate of reaction , as the matter exposed in the reaction increases.
3. catalyst :
catalyst increases the rate of reaction , and helps to attain the equillibrium faster.
