25 lut 2024 · The relationship between the equilibrium constant and the Gibbs free energy is given by the equation ΔG° = -RT ln(K), where R is the gas constant (8.314 J/mol·K) and T is the temperature in Kelvin. This equation allows us to calculate the standard Gibbs free energy change for a reaction at a given temperature.
16 gru 2022 · The equation for the Gibbs free energy is: G=H-T\cdot S G = H − T ⋅ S. Where: G G is the Gibbs free energy; H H is the enthalpy; T T is the temperature; and. S S is the entropy. The enthalpy can be defined in terms of other quantities, somewhat completing the formula for the free energy:
