CHMA11H3 Study Guide - Activation Energy

For the reaction A + B + C rightarrow D + E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction between A and B. The dependence of the reaction rate on the concentration of each reactant is given by the equation called the rate law. rate = k[A]^m[B]^n where k is a proportionality constant called the rate constant. The exponent m determines the reaction order with respect to A, and n determines the reaction order with respect to B. The overall reaction order equals the sum of the exponents (m + n). What is the reaction order with respect to A? Express your answer as an integer. What is the reaction order with respect to B? Express your answer as an integer. What is the reaction order with respect to C? Express your answer as an integer.
