Question

Given the reaction :

A(s)+ B(aq)-C(aq)+D(s)
Which change would increase the rate of reaction

Answer 1

To increase the rate of a reaction, we need to increase the frequency of successful collisions between the reactant molecules. One way to do this is by increasing the surface area of the reactants, which would allow more reactant molecules to come into contact with each other. Therefore, grinding the solid A into smaller pieces would increase its surface area and increase the frequency of collisions with B, which would increase the rate of the reaction.
