Assertion : Compressibility factor for hydrogen varies with...
Assertion : Compressibility factor for hydrogen varies with pressure with positive slope at all pressure.
Reason : Even at low pressure, repulsive forces dominate for hydrogen gas
Options
- AIf both assertion and reason are true and reason is the correct explanation of assertion
- BIf both assertion and reason are true but reason is not the correct explanation of assertion
- CIf assertion is true but reason is false
- DIf both assertion and reason are false.
Correct answer
A. If both assertion and reason are true and reason is the correct explanation of assertion
Step-by-step solution
In case of , compressibility factor increases with the pressure. At which shows that it is difficult to compress the gas as compared to an ideal gas. In this case, repulsive forces dominate.
