The Maxwell Distribution is a plot with the y-axis as the relative number of particles and the x-axis as the velocity. Each point on the curve tells us the relative number of particles or the fraction of particles that is at a certain velocity. The curves would be bell-shaped which means that the middle part would be the highest part of the curve. This just means that the middle range of velocities for a certain element at a certain temperature would be its most likely velocity.
On a single plot, qualitatively sketch the distribution of molecular speeds for
(a) Kr(g) at -50˚C
(b) Kr(g) at 0˚C
(c) Ar(g) at 0˚C.
