Which statement about kinetic energy is true?

a) it increases if a catalyst is added to the reaction.
b)it is not affected by temperature.
c) it is the energy required to form a new product.
d)it doesn't affect the collision of reacting substances.

I think the best answer from the choices listed above is option A. However, it should be noted that activation energy is different from kinetic energy. The former is the energy required for a reaction to proceed while the latter is the energy possessed by the molecules in motion. In some ways, they can be related but they should not be interchanged.
