NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The entropy change of the surroundings is equal to the enthalpy change of the system divided by the temperature of the system. | Reason (R): For a spontaneous process, the total entropy change is greater than zero.

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option B

Detailed Explanation

The assertion is true as the entropy change of the surroundings is given by ΔS_surr = ΔH_sys/T. The reason is also true but it explains a condition for spontaneity, not specifically why the assertion holds.
