Lowering the amount of reactants

The rate of reaction refers to the speed at which products are formed from the reactants.
The rate of reaction depends on several factors which include the concentration of reactants, temperature, presence of a catalyst, and surface area of reactants among others.
The rate of reaction increases with an increase in the concentration of reactants as there will be more collision between particles of reactants resulting in the formation of more products.
Catalysts speed up chemical reactions without being consumed by the reaction.
An increase in temperature increases the rate of endothermic reaction but decreases the rate of an exothermic reaction.
An increase in the surface area of reactants increases the rate of reaction due to the increased number of collisions between particles of reactants.
