Crms = <C 2 > 1/2 , (c) most probable C, C mp in MaxwellBolzmann distribution. Assume that T = 300K for all the case. 7. Prove that = > < 3 2 2 3 2 2 4 dC C kT mC kT m C exp / gives 2 1 8 / = > < M RT C , where C denotes the speed of a gas molecule B that has a mass m and M is a molar mass of B. 8. Plot a MaxwellBoltzmann distribution P(C) = 2 2 2 3 2 2 4 C RT MC RT M C = > < exp / using Excel or other software for N 2 at 200K and 400K in 0 C < 1500 m/s. 9. How much of the average translational energy E trans and rotational energy E rot do you expect for one mole of (a) Ar, (b) HCl, (c) C 2 H 2 , (d) NH 3 , (e) C 6 H 6...
