The entropy of activation
values in the absence and presence of inhibitor are negative.
Enthalpy and entropy of activation
decreased, while the Gibbs free energy increased with increased temperatures for the range shown in Table 5.
Whereas the negative values for entropy of activation
indicate that the activation complex has a more ordered or more rigid structure than the reactants and the reaction is slower than the normal(17).
