Problem: Calculate the root-mean-square velocity and kinetic energy of CO, CO2, and SO3 at 286 K .Which gas has the greatest velocity?

FREE Expert Solution

Recall that the molecular speed of a gas is given by:

mol. speed=3RTM


where R = gas constant, T = temperature, and M = molar mass of the gas.
