... The sign of ∆G indicates the direction in which a reaction moves to reach its equilibrium position. A reaction is thermodynamically favorable when its enthalpy, ∆H, decreases and its entropy, ∆S, increases. Substitut‑ ing the inequalities ∆H < 0 and ∆S > 0 into equation 6.2 shows that a reaction is ...
