Vedclass · Answer

(A) For hydrogen gas $(H_2)$,the compressibility factor $Z$ is defined as $Z = \frac{PV}{nRT}$.For $H_2$,$Z$ is always greater than $1$ at all pressures,and it increases linearly with pressure.This indicates that the gas is more difficult to compress than an ideal gas,which is due to the dominance of repulsive forces between the molecules even at low pressures.Therefore,both the Assertion and the Reason are correct,and the Reason correctly explains the Assertion.

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