JEE Main 2016 (09 Apr Online)

Question

A reaction at 1 bar is non-spontaneous at low temperature but becomes spontaneous at high temperature. Identify the correct statement about the reaction among the following:

Choose an option

Show full solutionCorrect option: D
Correct answer
DBoth ∆H and ∆S are positive

Step-by-step explanation

∆G = ∆H – T∆S (For Spontaneity) (∆G < 0)
So If  ∆H > 0  and  ∆S > 0 for spontaneity then the process is feasible at high temperature and non-feasible at low temperature.
