Question

The rate of a reaction , when the temperature is increased.

• A. increases
• B. decreases
• C. remains same

Answer 1

The correct option is A increases

Temperature is an important factor which affects the rate of a reaction. The kinetic energy, number of molecules with threshold energy and the speed of the molecules of reactants increase as the temperature increases.

As the number of molecules with threshold energy increases, the number of effective collisions also increase. Hence, the rate of the reaction increases with the increase in the temperature.
