Catalyst increases the rate of reaction

Question

Catalyst increases the rate of reaction (A) by decreasing Ea  (B) by increasing Ea  (C) by decreasing A (D) by increasing entropy

Tardigrade Admin · Accepted Answer

The reactant molecules have to acquire a certain amount of energy before they can react to yield products. This minimum value of energy for a reaction is known as energy of activation. Catalyst can change the rate of reaction by lowering the energy of activation.
