WebAug 17, 2014 · ΔG = ΔGo +RT ln( P c CP d D P a AP b B) This shows that if you increase the partial pressure of a product gas, ΔG becomes more positive. If you increase the partial pressure of a reactant gas, ΔG becomes more negative. EXAMPLE For the reaction 2A (g) + 2B (g) ⇌ C (g) + 3D (g) WebThe standard change in free energy, ΔG°, for a reaction is related to its equilibrium constant, K, by the equation ΔG° = -RTlnK.When ΔG° < 0, K > 1, and the reaction is product-favored at equilibrium. When ΔG° > 0, K < 1, and the reaction is reactant-favored at equilibrium. When ΔG° = 0, K = 1, and the reaction is at equilibrium under standard state conditions. methods for observing children https://eaglemonarchy.com
