ABSTRACT

Chemical kinetics is the study of the rates of chemical reactions, the factors that affect these rates, and the reaction mechanisms by which reactions occur. Reaction rates vary greatly – some are very fast (burning) and some are very slow (disintegration of a plastic bottle in sunlight). A reaction mechanism is the step by step sequence of elementary reactions by which overall chemical process occurs. A mechanism describes in detail exactly what takes place at each stage of an overall transformation. It also describes each reactive intermediate, activated complex, and transition state, and which bonds are broken (and in what order), and which bonds are formed (and in what order). A complete mechanism must also account for all reactants used, the function of a catalyst, stereo chemistry, all products formed and the amount of each. It must also describe the relative rates of the reaction steps and the rate equation for the overall reaction. Mechanisms describe in a step-wise manner the exact collisions and events that are required for the conversion of reactants into product.
