Document Summary
Units on rate are always m s-1 (unless told otherwise) Rate law usually defined in terms of reactants only. If 0, that means regardless of that reactant"s concentration, it does not affect the rate. Can be negative, if it is then it is an inhibitor. Can also be a fraction (but we won"t see that in class) Determine rate law, exponents, and value for k. 0=0 the concentration changes but the rate does not change. 1=the concentration changes with the same multiplier as the rate (2x, 5x) 2 or 3 or higher= the concentration changes and. Describes how rate of reaction varies with [x] Also useful to be able to relate concentration to time lecture notes page 1. Also useful to be able to relate concentration to time. Similar time dependence seen for all reactions with similar reaction order. Reaction whose rate depends on the concentration of one of the reactants raised to the first power.
