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

Hope this helps

_{2}at 25 deg C and then substitute the mass of a CO_{2}molecule and solve for the temperature.Hope this helps
