PREPARATORY PROBLEMS (Theoretical)
... The natural tendency of any chemical reaction to proceed in a certain direction at constant temperature and pressure is determined by the sign of the Gibbs energy of the reaction, DG. This is the universal principle. If DG < 0, the reaction can proceed predominantly in the forward direction (a produ ...
