Which equation represents the relationship between free energy change (∆G), enthalpy change (∆H), temperature (T), and entropy change (∆S)?
Which equation represents the relationship between free energy change (∆G), enthalpy change (∆H), temperature (T), and entropy change (∆S)?
- $∆G = ∆H * T∆S$
- $∆G = ∆H / T∆S$
- $∆G = ∆H + T∆S$
- $∆G = ∆H - T∆S$ (correct)
