NEET Physics Entropy Assertion Reason Question
Assertion (A): For a reaction where both enthalpy and entropy changes are positive, the reaction is spontaneous at high temperatures. Reason (R): A positive entropy change indicates an increase in the disorder of the system.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false.
Correct Answer
Detailed Explanation
From the NCERT context, positive entropy change increases disorder, and the reaction is spontaneous at high temperatures when both enthalpy and entropy changes are positive.
