In the case of positive deviation from an ideal gas
Options:
Answer:
C
Solution:
Positive deviation means Z = PV/nRT > 1, which occurs when repulsive interactions dominate, i.e. the finite size (excluded volume) of the molecules is significant. Attractive interactions lower the pressure and give Z < 1 (negative deviation). Hence the cause is finite molecular size with PV/nRT > 1. Ans: (c)
