Delta g with pressure
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. WebMay 9, 2015 · Delta G is the symbol for spontaneity, and there are two factors which can affect it, enthalpy and entropy. Enthalpy - the heat content of a system at constant pressure. Entropy - the amount of disorder in …
