An increase in temperature increases the reaction rate because more collisions will have enough energy to exceed the activation energy a greater fraction of the collisions have the correct orientation of molecules temperature acts as a catalyst in chemical reactions. What will happen on activation energy?a. The activation energy of the reaction will decrease. b. The activation energy of the reaction will increase. c. Remains the same

The activation energy of the reaction will decrease.

Explanation:

Basically, a catalyst lowers the activation energy of a chemical reaction. The involvement of a catalyst creates an alternative pathway for reaction with lesser activation energy. This enables the reaction to proceed faster. Hence a catalyst increases the rate of reaction by lowering the activation energy.

i'm wiling to try and you : )

it is stable as it is in group 0 which have full outer shells of electrons
