Chemistry - Real Gas Question with Solution | TestHub

(a) True: at high pressure the excluded-volume (repulsive) correction b dominates, pushing Z above 1. (b) True in the one-dimensional sense: along any single dimension the molecular velocities are equally positive and negative, so the average of the one-dimensional velocity is zero. (c) True: the Maxwell-Boltzmann fraction depends on M and T only through the ratio M/T, and (M/2)/(T/2) = M/T. (d) False: near the critical point attractive and volume effects are strongest and gases deviate most from ideality. Hence (a), (b), (c).
