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:, ∆ H is negative while ∆ S is positive, Both ∆ H and ∆ S are negative, ∆ H is positive while ∆ S is negative, Both ∆ H and ∆ S are positive

MARKS App · Accepted Answer

∆ 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.
