For a particular reversible reaction at temperature T. Delta H and Delta S were found to be both +ve. If T_(e) is the temperature at equilibrium, the reaction would be spontaneous when

Answer»

`T_(E)` is five times T
`T = T_(e)`
`T_(e) GT T`
`T gt T_(e)`

Solution :`Delta G = Delta H - T Delta S`
At EQUILIBRIUM, `Delta G = 0`
`0 = Delta H - T Delta S`
or `T_(e) Delta S = Delta H`
`T_(e) = (Delta H)/(Delta S)`
Since it is an endothermic reaction, its is favoured by high temperature so that `T gt T_(e)`.
