The enthalpy change for a given reaction...

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

A

Can be `-ve` but numerically latger than `-x//298 cal K^(-1)`

B

Can be `-ve`, but numerically smaller than `x//298 cal K^(-1)`

C

Cannot be negative

D

Cannot be positive

To solve the problem, we need to analyze the relationship between enthalpy change (ΔH), entropy change (ΔS), and Gibbs free energy change (ΔG) for the reaction occurring at 298 K. The key equation we will use is: \[ \Delta G = \Delta H - T \Delta S \] Given: - ΔH = -x cal mol\(^{-1}\) (where x is a positive value) ...

The entropy chnge for a non-spontaneous reaction is 140 J/K.mole at 298 K. The reaction is_____________.

Gibbs-Helmoholtz equation relates the free energy change to the enthalpy and entropy changes of the process as (DeltaG)_(PT) = DeltaH - T DeltaS The magnitude of DeltaH does not change much with the change in temperature but the enrgy factor T DeltaS changes appreciably. Thus, spontaneity of a process depends very much on temperature. The enthalpy change for a certain reaction at 300K is -15.0 kcal mol^(-1) . The entropy change under these conditions is -7.2 cal K^(-) mol^(-1) . The free enegry change for the reaction and its spontaneous//nonspontaneous character will be

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?
