Kinetics, Rate Laws, Reaction Mechanism
Define rate of reaction for given reactions in terms of reactants and products
Rate law as experimental observation of effects of changing concentrations on rates
Order of reaction: exponent in rate law expression for component
Overall order = sum of individual orders
Integrated rate expressions for first and second order reactions; how to plot them
First order: t versus ln[concn]; second order t versus 1/[concn]
A reaction mechanism is a hypothesis to explain observed rate laws
Elementary reactions are hypothetical; add together to get mechanism and overall rate law
Learn to interpret some simple rate laws in terms of elementary reactions, for example RBr reacting with OH- where R = ethyl; and tert-butyl
Rate limiting or slowest step limits observed rate of a multi-stage reaction
