Question:

Which of the following is the correct Gibbs equation?

Options:

 

\(\Delta G \text{ = } \Delta H \text{ + }T\Delta S \)

\(\Delta G \text{ = } \Delta H \text{ – }T\Delta S \)

\(\Delta G \text{ = } \Delta H \text{ – }2T\Delta S \)

\(\Delta G \text{ = } \Delta H \text{ – }3T\Delta S \)

Correct Answer:

\(\Delta G \text{ = } \Delta H \text{ – }T\Delta S \)

Explanation:

or any process, the change in Gibbs free energy (\(\Delta  G\)) is given by the equation,

\(\Delta G \text{ = } \Delta H \text{ – }T\Delta S \)


Where (\(\Delta H\)) is the enthalpy change, (\(\Delta S\)) is the entropy change and T is the absolute temperature.
