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

###### FREE Expert Solution

Recall that the kinetic energy of a gas is given by:

$\overline{){{\mathbf{KE}}}_{{\mathbf{avg}}}{\mathbf{=}}\frac{\mathbf{3}}{\mathbf{2}}{\mathbf{RT}}}$

where R = gas constant, T = temperature
