According to the Kinetic Molecular Theory, as the volume of a gas increases:

the number of particle impacts per unit area increases
the temperature must change
the total number of particle impacts increases
the number of particle impacts per unit area decreases

aaronq · Answer

if you increase the volume and you don't change the number of particles, there will be less particles per unit and therefore the probability for collision is decreased
