A reaction A + B ------> C + D + q is found to have entropy change. The reaction will be:
(1) Possible at high temperature
(2) Possible only at low temperature
(3) Not possible at any temperature
(4) Possible at any temperature.
(4) Since the reaction is Exothermic (AH < 0) and has AS > 0, therefore, it is feasible at all temperatures because both the factors favour spontaneity.
