Question

Four different identical vessels at same temperature contains one mole each of C2H6, CO2, Cl2 and H2S at pressures P1, P2, P3, P4 respectively. The value of Van der Waal's Constant 'a' for C2H6, CO2, Cl2 and H2S is 5.562, 3.640, 6.579 and 4.490 atm. L^2. mol^-2 respectively. Then -

A) P3 < P1 < P4 < P2
B) P1 < P3 < P2 < P4
C) P2< P4 < P1 < P3
D) P1 = P2 = P3 < P4
