Assertion: Compressibility factor for hydrogen varies with pressure with positive slope at all pressures.
Reason: Even at low pressure, repulsive forces dominate hydrogen gas.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
Explanation:
In case of hydrogen, Z increases with pressure. At 273K, Z > 1. which shows that it is difficult to compress the gas as compared to ideal gas. In this case repulsive forces dominate.
