How can the rate of a reaction be decreased?

(a) lowering the amount of reactants

(b) adding a catalyst

(c) having more surface area

(d) raising the temperature

Option A

Lowering the amount of reactants

Explanation:

To reduce the rate of chemical reaction, one can reduce temperature or surface area. The addition of catalysts increases rate of reaction but decreasing the amount of reactants decreases rate of reaction. Therefore, from the choices provided, choice A is correct.
