How can the rate of a reaction be increased

decreasing the amount of reactants

having more surface area

diluting a solution

lowering the temperature

The correct answer is having more surface area

Explanation:

Reaction rate can be defined as the amount of substrate is converted into product per unit time .Reaction rate also called reaction velocity.

   The reaction rate can be increased by increasing the surface area so that many reactant molecules can participate in the reaction as a result the reaction rate is being increased.

  On the other hand decreasing the amount of reactant,diluting the solution and lowering the temperature decreases the reaction rate.
