NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing a system in thermal equilibrium with its surroundings. According to the principles of thermodynamics, which expression correctly represents the condition for a spontaneous process occurring within this system?
A
T∆S_sys - ∆H_sys > 0
B
T∆S_sys + ∆H_sys > 0
C
∆S_sys - T∆H_sys > 0
D
∆H_sys - T∆S_sys > 0
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, for a process to be spontaneous, the condition T∆S_sys - ∆H_sys > 0 must hold, which aligns with the equation for spontaneity derived from entropy changes.
