If the Van der Waal's equation for 1 mole of the gas is represented as Z = PV/RT = 1 + B'P + C'P2 + ..., in place of Z = PV/RT = 1 + B/V + C/V2 + ..., the correct relation(s) is/are
Options:(select one or more)
Answer:
A, C
Solution:
Substitute P = (RT/V)(1 + B/V + ...) into Z = 1 + B'P + C'P2 + ...: the 1/V term gives B = B'RT (a ✓, b ✗). The 1/V2 term gives C = B'RT·B + C'(RT)2 = B2 + C'(RT)2 (c ✓). Consequently C' = (C − B2)/(RT)2, not C/(RT)2 (d ✗). Hence (a) and (c).
