How can one determine the equilibrium constant (Keq) from the change in Gibbs free energy (G)?

To determine the equilibrium constant (Keq) from the change in Gibbs free energy (G), you can use the equation: G -RT ln(Keq), where R is the gas constant and T is the temperature in Kelvin. By rearranging this equation, you can solve for Keq as Keq e(-G/RT).
