An exothermic reaction A---> B is spontaneous in the backward direction. What will be the sign of ΔS for the forward reaction?

Backward reaction will be endothermic. Thus, energy factor opposes the backward reaction .As backward reaction is spontaneous, randomness factor must favour, i.e., ΔS will be +ve for backward reaction or it will be –ve for forward reaction.
