AIIMS 2001 Chemistry Gibbs Free Energy MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following is always feasible? ΔH = TΔS

A

ΔH = TΔS

B

ΔH (+ve), TΔS (−ve) and ΔH > TΔS

C

ΔH (−ve), TΔS (+ve) and ΔH < TΔS

D

ΔH (−ve), TΔS (−ve) and ΔH > TΔS

Correct Answer

Option C

Detailed Explanation

A process is feasible if ΔG = ΔH − TΔS is negative. If ΔH is negative and TΔS is positive, ΔG is always negative.
