Increasing the Temperature of a Reaction Will Do All of the Following

Question

Increasing the temperature of a reaction will do all of the following EXCEPT
A)increase the reaction rate.
B)increase the number of molecules attaining activation energy.
C)increase the number of molecular collisions.
D)increase the activation energy.
E)increase kinetic energy of the molecules.

Accepted Answer

Increasing the temperature will not increase the activation energy of a reaction. Activation energy is a constant value for a given reaction and is not affected by changes in temperature. Increasing temperature will increase the kinetic energy of the molecules, making them more likely to collide and reach the activation energy. This, in turn, increases the reaction rate.
