# What does it mean if a process is enthalpy-driven?

$\Delta G = \Delta H - T \Delta S$
When $\Delta G < 0$, the process is energetically favorable.
When a system is enthalpy driven, generally $\Delta H < 0$ to compensate for $\Delta S < 0$. To be sure, it occurs spontaneously at lower temperatures, and nonspontaneously at higher temperatures.
