The entropy change for a certain non-spontaneous reaction is 150 J/K.mol. at 298 K. The minimum value of DeltaH for the reaction is _________.

The following reaction is non-spontaneous

A reaction is non-spontaneous when:

The oxidation of iron occurs as: 4Fe(s) + 3 O_(2)(g) to 2Fe_(2)O_(3)(s) The enthalpy of formation of Fe_(2)O_(3) is - 824.2 kJ mol^(-1) and entropy change for the reaction is -549 J K^(-1) mol^(-1) at 298 K. Inspite of negative entropy change of this reaction, why is the reaction spontaneous at 298 K?

The enthalpy change for a given reaction at 298 K is -x cal mol^(-1) . If the reaction occurs spontaneously at 298 K , the entropy change at that temperature
