Chemistry - Real Gas Question with Solution | TestHub

(a) True: at T_B the second virial coefficient B = b − a/RT vanishes, so dZ/dP $\to$ B/RT = 0 at low P. (b) True: along any single dimension velocities are equally positive and negative, so their average is zero. (c) True: the Maxwell-Boltzmann fraction depends on M/T alone, and 2M/2T = M/T. (d) False: deviations from ideality are largest near the critical point. Hence (a), (b), (c).
