The correct thermodynamics conditions for the spontaneous reaction at all temperature isA. `Delta H lt 0` and `Delta S gt 0`B. `DeltaH lt 0` and `DeltaS lt 0`C. `Deltah lt 0` and `DeltaS =0`D. `DeltaH gt 0` and `Delta S lt 0`

Answer» Correct Answer - a,c
A reaction is spontaneous at all temperatures,if both energy factor an anetropy factor favour the process, i.e., `DeltaHlt0` and`DeltaSgt 0` or when energy factor favours but entropy factor has no roleto play, i.e.,`DeltaHlt0` and`DeltaS = 0`.
