Document Summary

An integrated rate law is an equation that expresses the concentrations of reactants or products as a function of time. R = k[a] (this will be given in the question) Integrated rate law= ln[a] = ln[a]o kt. The graph of ln[a] against time is always a straight line if the reaction is first order only. Half- life: time taken for initial concentration to decrease to half: half-life of a first order reaction does not depend on concentration, whatever the initial concentration, the half life is always the same.

The rate depends on the pt plate, and not n2o. If the pt plate is saturated, increasing the concentration of n2o will not increase the rate of reaction. Half-life: time taken for initial concentration to decrease to half. [a] = [a]o kt: half- life of a zero-order reaction depends on concentration.
