Calculate the standard free energy change
WebThe standard change in free energy, ΔG°, for a reaction applies only when the reactants and products are in their standard states.In all other circumstances, we must consider the nonstandard free energy change, ΔG, which can be calculated from ΔG° using the equation ΔG = ΔG° + RTlnQ.In this equation, R is the appropriate gas constant (8.314 … WebThe standard free energy change for a reaction may also be calculated from standard free energy of formation \((\text{Δ}{G}_{\text{f}}^{°}),\) values of the reactants and products involved in the reaction. The standard free energy of formation is the free energy change that accompanies the formation of one mole of a substance from its elements in their …
