Chemistry-Gibbs Free Energy
NEET Chemistry Gibbs Free Energy MCQ Question
Type: MCQ-diagram based-Easy-Class 11
Consider a diagram showing a graph of Gibbs Free Energy (G) versus Temperature (T) for a chemical reaction. The graph displays different regions based on the sign of ΔG at various temperatures. Which of the following correctly describes the condition when the reaction is spontaneous at high temperatures?
A
ΔH is positive and ΔS is positive.
B
ΔH is negative and ΔS is negative.
C
ΔH is negative and ΔS is positive.
D
ΔH is positive and ΔS is negative.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, a reaction is spontaneous at high temperature when both ΔH and ΔS are positive, as this results in a negative ΔG at high T.
