Assertion : For an isothermal reversible...

Assertion : For an isothermal reversible process Q = - w i.e., work done by the system equals the heat absorbed by the system.
Reason : Enthalpy change `(DeltaH)` is zero for isothermal process.

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 assertion is false but reason is true.

Text Solution

Verified by Experts

The correct Answer is:
D
Assertion: The enthalpy of any elementary substance in the standard state is zero but the entropy of the same is not zero.
Reason: At zero degree absolute (0 K), volume becomes zero and the constituent particles become motionless.
