Knowing colligative properties is key Molecularity = number of species that must collide to produce the reaction indicated by the step Rate law is always determined first. A mechanism can never be proved absolutely Mechanism must agree with experimentallydetermined rate law Sum of elementarysteps must be the overall balanced equation Activation energy = 'threshold energy' transition state Catalyst speeds up reaction without being consumed (does not show up in actual balanced equation) Catalyst appears in the first elementarystep and is canceled out somewherealong the way Catalyst LOWERS activation energy of a reaction and increases effectivecollison rate by providing a different pathway for the reaction ( lower-energy pathway) Intermediatescannot be expressed in your final rate law (generally) Intermediatescan be rewritten (substituted) with their reactants in previous "fast" elementarysteps.
