Document Summary

Chma11 lecture 23: relating free energy (g) to the equilibrium constant (k) Free energy, spontaneity, and equilibrium: every chemical reaction consists of both forward and reverse reactions, the direction of spontaneous change is the direction in which the free energy decreases, free energy and k value. If k is less than 1: the change in free energy between the forward and reverse reactions will be positive, this means that the reverse reaction is spontaneous, reaction will thus shift left. If k is equal to 1: this means that the change in free energy between the forward and reverse reactions will be 0, this means the reaction is at equilibrium, reaction will not shift. Temperature dependence of the equilibrium constant: we have already made an equation that related the standard gibbs energy change for a reaction to the equilibrium constant for a reaction, the equation is below.
