where C is the concentration of components such as Jatropha curcas triglyceride (JTG), Jatropha curcas diglyceride (JDG), Jatropha curcas monoglyceride (JMG), glycerol (GL), Jatropha curcas methyl ester (JME), and methanol (MeOH) and k is the effective rate constant of each stepwise reaction.
For these reasons stepwise reactions cannot go on under a normal reaction mechanism.
From Table 2, it can also be seen that the rate constants (k) also increased as the reactions progressed through the three stepwise reactions. The rate constants for the forward reactions were considerably higher than those for the reverse reactions.
He began with studies of the application of Marcus Theory to organic reactions, then developed Multidimensional Marcus Theory to treat concerted reactions in terms of the hypothetical stepwise reactions
, and recently developed No Barrier Theory, which allows calculation of the rate constants for a great many reactions in solution with no adjustable parameters.
