Document Summary

Kinetics involves the study of the rates and mechanisms of chemical reactions. We saw from thermodynamics that we can predict with confidence the extent of a chemical reaction, i. e. , thermodynamics can tell you if a reaction will move in the forward direction when g < 0. We can also determine whether products or reactants are favoured at equilibrium, e. g. , g = rtlnkeq. But this tells us absolutely nothing about how quickly or slowly a reaction takes place. Reactions can have a very large and negative g and still take years to produce a substantial amount of products. The study of chemical kinetics allows you to determine: reaction rates (how fast, slow) factors which affect reaction rates (such as concentrations & temperature) reaction mechanisms. 111 the reaction takes to proceed to the products). they tend to go slower as the reactants are used up.
