Assertion (A): Compressibility factor for hydrogen varies with pressure with positive slope at all pressures
Reason (R):  Even at low pressures, repulsive forces dominate in hydrogen gas. 

A

A & R are true, R explains A

B

A & R are true, R does not explain A

C

A is true R is false

D

A is false R is true

Text Solution

Verified by Experts

The correct Answer is:
A
Z for `h_1 = 1 + P (b/(RT))`
i.e., `Z > 1 implies ` repulsive forces.
