Can anyone help/show me how to calculate the mean thermal velocity of nitrogen at 25 C?

OpenStudy (anonymous):
The average kinetic energy of a nitrogen molecule at temperature T is \[\frac{5}{2} kT \] so set that equal to kinetic energy and solve.
OpenStudy (anonymous):
You should use 3/2 kT, not 5/2. The rotational kinetic energy does not contribute to the translational velocity.
