What is altered by a catalyst?

a) average kinetic energy of products

b) activation energy

c) difference between the energies of products and reactants

d) average kinetic energy of reactants

Respuesta :

Answer:Effect of Catalysts on the Activation Energy. Catalysts provide a new reaction pathway in which a lower Activation energy is offered. A catalyst increases the rate of a reaction by lowering the activation energy so that more reactant molecules collide with enough energy to surmount the smaller energy barrier.
