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.
