NEET Physics (general) MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about the relationship between enthalpy change (∆rH°), entropy change (∆rS°), and Gibbs free energy change (∆rG°) is correct?
A
A large positive ∆rH° indicates that the reaction is likely to favor the formation of products.
B
A large negative ∆rG° suggests that the reaction is spontaneous at all temperatures.
C
If ∆rS° is positive, the reaction will always be spontaneous regardless of temperature.
D
For strongly endothermic reactions, ∆rH° is positive and K will be much smaller than 1.
Correct Answer
Option D
Detailed Explanation
For strongly endothermic reactions, the value of ∆rH° may be large and positive, leading to K being much smaller than 1, indicating that the reaction is unlikely to form much product (Chunk 4).
