At what temperature would CO2 molecules have an rms speed equal to that of H2 molecules at 25 degrees C?
Cory,
The relationship is μ rms = (3RT/M)½
where
μrms = root mean square velocity in m/sec
R = ideal gas constant = 8.3145 (kg·m2/sec2)/K·mol
T = absolute temperature in Kelvin
M = mass of a mole of the gas in kilograms.

All you have to do is calculate the speed for H_{2} at 25 deg C and then substitute the mass of a CO_{2} molecule and solve for the temperature.
