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.
