Which factors affect the rate of a reaction?

To determine
The factors that affect the rate of reaction.

Explanation of Solution

The rate of reaction depends upon the following factors;

(1) Temperature

(2) Concentration

(3) Surface area

(4) Catalyst

The rate of reaction increases with increase in temperature. In a chemical reaction, reacting molecules or atoms collide with each other with enough kinetic energy to break bonds. If heat is given to the system and raises the temperature, the kinetic energy of the molecules will be increased. This causes more and more collision of atoms or molecules in a chemical reaction and hence the reaction rate increases.

The rate of reaction increases with increase in the concentration of reactants. The reacting molecules are more closely packed. Therefore, more collision occurs and hence the rate of reaction increases...
