NEET Chemistry Spontaneity MCQ Question

Type: MCQ-conceptual-Medium-Class 11

In isolated system, find the condition for spontaneous reaction.

A

ΔU = 0, ΔS = 0, ΔG = 0

B

ΔU < 0, ΔS > 0, ΔG < 0

C

ΔU = 0, ΔS > 0, ΔG < 0

D

ΔU < 0, ΔS < 0, ΔG < 0

Correct Answer

Option C

Detailed Explanation
