2 ala 2 on a day when the atmospheric pressure is 750 mm Hg2Atwhat temperature would CO2 molecules have a n mns speed equal to thatof H2 molecules at 25°C?03nt mean square average and |
| Answer» <p>square root of 3kT/M, so this question is based on the mass ratio.</p><p>for He, the rms speed is = sqrt of 3k(273+25)/4for CO2, the same rms speed is = sqrt of 3kT/44</p><p>(298)/4 = T/44; T = 3278 K</p> | |
