CHEM 105bL Lecture Notes - Lecture 6: Rate-Determining Step, Reaction Mechanism, Rate Equation
Document Summary
Reaction mechanism: reaction mechanism: the series of steps by which. An overall chemical reaction occurs: elementary step: cannot be broken down into simpler steps. You can write the rate law from stoichiometry: reaction intermediate: forms in one step and is consumed in a later step. All elementary steps must add up to give the overall reaction. The rate law written from the rate determining step matches the experimentally determined rate law: catalysis, a catalyst is a substance that increases the rate of a chemical reaction. i. It lowers the ea of the reaction: homogeneous catalyst: in the same phase as the reactants, heterogeneous catalyst: in a different phase than the reactants, enzyme: a biological catalyst. In a reaction mechanism, a catalyst will be consumed in one step and reproduced in a later step.
