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