CHEM 113 Study Guide - Final Guide: Rate Equation, Stoichiometry
Document Summary
Rate = - [a] / t = 1/2 [ [b] / t] For the reaction below, express the rate of the reaction with respect to each of the reactants and products. 2n2o (g) 2n2 (g) + o2 (g) Rate = - [n2o] / t = [n2] / t = [o2] / t. In the first 10 seconds of a reaction, 0. 018 moles of o2 is produced in a reaction vessel with a volume of 0. 250 l. Rate = [o2] / t = [0. 018 moles o2 / 0. 250 l] 0m / 10 s 0 s. The rate law: describes how the rate of a chemical reaction depends on the concentration of reactants (for now, assume insignificant reverse reactions and a constant temperature. ) Form of a rate law for the reaction: aa + bb cc. A rate law cannot be determined directly from the stoichiometry of the reaction.
