Answer Details
The number of effective collisions of molecules of the reactants decreases as the volume of the system is increased. As the volume of the system increases, the space available for the molecules to collide with each other decreases. This leads to a decrease in the frequency of collisions, which in turn decreases the number of effective collisions. Effective collisions are those collisions between reactant molecules that have enough energy and correct orientation to lead to the formation of products. When the volume of the system is increased, the number of collisions decreases, and therefore the number of effective collisions also decreases.
