According to KMT, at constant pressure and temperature, the frequency and force of molecule-wall collisions are constant. So increasing the number of gaseous molecules will require a proportional increase in the container volume in order to yield a decrease in the number of collisions per unit area to make up for the increased frequency of collisions. What gas law is KMT explaining?

Boyle's Law

Explanation:

If we increase the volume of a gas, its pressure will decrease that is why in this question the pressure was decreased to yield the decrease in the number of collisions.

This is Boyle's law which states that the pressure of a gas is inversely proportional to the volume of its container.

It is expressed mathematically as P₁V₁ = P₂V₂

where the subscripts refer to intial and final conditions.
