    Answer: Option (d) is the correct answer.

    Explanation:

    According to kinetic molecular theory, particles of a gas are constantly in a random motion.

    Also, there is large gap between the particles of a gas as compared to the size of molecules themselves.

    So, it means that as the volume of a gas increases the number of particle impacts per unit area decreases because there is large space between molecules. Hence, less number of particles will occupy in per unit area.

    Thus, we can conclude that according to the Kinetic Molecular Theory, as the volume of a gas increases the number of particle impacts per unit area decreases.

    As the volume of a gas increases at constant temperature, the number of particle impacts per unit area decreases.

    There is the same number of impacts, but they are spread over a larger surface area.

    Thus, the number of impacts per unit area decreases.
