Solution

In a reaction, the rate of the reaction depends upon the particle size of the solid reactant as the reaction takes place on the surface only. Smaller the particles are, the more will be their total surface area and faster will be the rate of the reaction.

Hence, zinc powder reacts much faster with dil. $H_{2} {SO}_{4}$ than does granulated zinc..
