The average speed is a little larger than the most probable speed. For N2 at 25ºC, the average speed is 475 m/sec. The root-mean-square speed is the speed that corresponds to the average kinetic energy of the molecules.

Explanation:
What is the average molecular speed?
=> The root-mean-square speed measures the average speed of particles in a gas, defined as vrms=√3RTM v r m s = 3 R T M .
