Assertion: Compressibility factor for hy...

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

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
A
In case of H2, compressibility factor increases with the pressure. At 273 K, Z > 1 which shows that it is difficult to compress the gas as compared to ideal gas. In this case repulsive forces dominate.
