• The standard Gibbs free energy change of reaction (∆G°) is related to the equilibrium constant (Keq).
• The standard Gibbs free energy change of reaction (∆G°) is related to the equilibrium constant (Keq).
• The equilibrium constant is related to both the ∆H° and the ∆S° in the following way: ln Keq = ∆H°/(RT) + ∆S°/R.
• The equilibrium constant is related to both the ∆H° and the ∆S° in the following way: ln Keq = ∆H°/(RT) + ∆S°/R.
• At high temperatures, ∆S° determines whether ∆G° is positive or negative; at low temperatures, ∆H° determines whether ∆G° is positive or negative.
• At high temperatures, ∆S° determines whether ∆G° is positive or negative; at low temperatures, ∆H° determines whether ∆G° is positive or negative.
