the reactant must collide

Answer 2

GOOD EVENING FRIEND

FOR A REACTION TO START; ENERGY IS REQUIRED. WE CALL IT ACTIVATION ENERGY.

Activation energy is the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place.

Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.  The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

HOPE THIS HELPZZ
