Pseudo Steady State Hypothesis (PSSH). Chapter 1. Reaction Rates. What makes “superglue” bond instantly while Elmer’s glue does not?. What factors determine how quickly food spoils?. Why do “glow sticks” last longer when stored in the freezer?. The reaction mechanism is the . series of elementary steps. . by which a chemical reaction occurs.. The sum of the elementary steps must give the overall balanced equation for the reaction. The mechanism must agree with the experimentally determined rate law. Objectives. To monitor the progress of an enzyme catalyzed reaction (Acid phosphatase).. To determine the initial rate of the reaction (. V. i. ).. Important terms and points:. Enzyme kinetics. The central approach for studying the mechanism of an enzyme-catalyzed reaction is to study enzyme kinetics. . Lecture 14 . Reaction Rates. Recall that we defined the rate of reaction as the rate of production of the products, or equivalently, the rate of consumption of the reactants.. Reaction rates for elementary reactions depend on:.
