This relationship allows us to relate the standard free energy change to the equilibrium constant. When delta g is equal to zero and k is around one, the reaction is at equilibrium. It is important not to confuse the equilibrium constant with a rate constant of reaction, since they can both be represented by the letter k. In this equation, q is the reaction quotient and is defined the same manner as kk except that the concentrations or pressures used are not necessarily the equilibrium values. K is the equilibrium constant, meaning it is products divided by reactants when a reaction is at equilibrium. The greater the e° cell of a reaction the greater the driving force of electrons through the system, the more likely the reaction will proceed (more spontaneous).
