Gibbs Free Energy - Physical Chemistry Quiz

For constant temperature, Gibbs free energy is defined as:

$\Delta G = \Delta H - T \Delta S ,$

Where , $\small \Delta G$ is the change in Gibbs free energy, $\small \Delta H$ is the change in enthalpy, $\small T$ is temperature, and $\small \Delta S$ is the change in entropy.

Given that a system is spontaneous, which of the following states are possible?

I. $\Delta G<0, \Delta S>0, \Delta H<0$

II. $\Delta G<0, \Delta S<0, \Delta H>0$

III. $\Delta G<0, \Delta S>0, \Delta H>0$

IV. $\Delta G>0, \Delta S<0, \Delta H>0$
