Chemistry 112 – Day 10 (09/30/2019)KineticsReaction MechanismsoReaction mechanisms are the chemical steps which lead to an overall reaction.oEach step is called an elementary step.Sum of elemental steps = overall reactionMolecularity is used to describe the elementary steps.Unimolecular, bimolecular, termolecularoCompounds that appear in the elementary steps but not in the overall reaction are intermediatesoRate laws for elementary steps can be derived without the need for experimentaldataoA reaction mechanism is first proposed and then tested experimentallyThe Rate-Determining StepoThe elementary step that is much slower than the rest of the steps is the rate-determining step.oThis step is related to the overall rate law that you experimentally determine.Proposed MechanismsoTwo conditions must be satisfied for a proposed mechanism to be valid.The sum of the elementary steps must be the overall reaction.
