Chemical Thermodynamics Part 1

∆G=∆H−T∆S
Since ∆G=∆H−T∆S for an endothermic reaction,
∆H=+ve and at low temperature ∆S=+ve
Hence ∆G=(+)∆H−T(+)∆S
and if T∆S<∆H (at low temp)
∆G=+ve (non spontaneous)
But at high temperature, reaction becomes
spontaneous i.e. ∆G=− ve.
because at higher temperature T∆S>∆H.
