helium > nitrogen dioxide > xenon > oxygen are the order of increasing average molecular speed

All gases are thought to have the same kinetic energy at the same temperature, or in other words... We may simply use the order of decreasing molecule mass to assign molecular speed, going from quickest to slowest, because it follows that the Lighter gases are traveling Faster.

What is average molecular speed?

The continuous motion and optimally elastic collisions of gas particles are explained by the Kinetic Molecular Theory of Gases. Until they collide with another particle, gas particles always move in a straight line and are found in a constant state of random motion. Additionally, it explains how a bunch of gas particles' average kinetic energy is inversely related to temperature. A group of molecules' collective speed in a perfect gas environment can be determined.
