The change in entropy, Delta Sis positive for an endothermic reaction. If enthalpy change Delta Hoccurs at the same temperature T, then the reaction is feasible

Answer»

at all temperatures
when `Delta H gt T Delta S`
when `Delta H LT T Delta S `
when `Delta H = T Delta S`

Solution :We know `DeltaG = Delta H - T Delta S`(GIBBS Helmholtz EQUATION)
For endothermic REACTION `Delta H` = +ve and also given `Delta S` = +ve. The reaction is feasible when `Delta G` = -ve. The `Delta G`value will be -ve only when `Delta H lt T Delta S`
