Which of the following graph is correct for hydrogen gas at 0°C?
Options:
Answer:
B
Solution:
The Boyle temperature of H2 is about 110 K, far below 0°C (273 K). Above TB the compressibility factor Z = PV/nRT > 1 at all pressures — repulsions dominate — so at every volume H2 exerts a higher pressure than an ideal gas at the same V and T. The H2 curve lies above the ideal-gas hyperbola throughout: graph (b). Confirms Ans (b).
