At a certain temperature 'T', endothermic reaction `A rarr B` proceeds virtually to the end. Determine the sign of `Delta S` for the reaction `A rarr B` and `Delta G` for the reverse reaction `B rarr A`.

Explanation

`Delta S = +ve, Delta H = +ve, Delta G = -ve` and the reaction proceeds virtually to the end. The in reverse reaction `B rarr A, Delta S = -ve, Delta G = +ve`.
