It is proportional to the naural log of the ratio of the rate constant to the frequency factor.
When this quantity is added to a system, the system will take the conformation that is closest to the reactants in free energy, as stated by the Hammond Postulate. It is proportional to the naural log of the ratio of the rate constant to the frequency factor. The Arrhenius equation also can be plotted, and the negative slope of the plot is this quantity divided by the ideal gas constant. When this quantity is negative, the rate of a reaction will decrease when the temperature is increased. Catalysts lower this quantity without affecting the products or the reactants of the raction. FTP, name this term defined as the energy that must be overcome in order for a chemical reaction to occur.
When this quantity is added to a system, the system will take the conformation that is closest to the reactants in free energy, as stated by the Hammond Postulate.
