Another way to determine the orders with respect to reactants in a rate law is the method of initial rates, which we did not cover in class but is still important to be familiar with. An example of this method is provided in Example 18.3 on page 761 of your textbook; a Google search for method of initial rates should provide additional guidance. Analyze the data below, using the method of initial rates, to write the rate law for the reaction below: A(aq) + B(aq) + C(aq) > ABC(aq) [A], M [B], M [C] Initial rate, M/s 0.0123 0.0123 0.0123 0.00123 0.0123 0.0246 0.0123 0.01107 0.0246 0.0123 0.0123 0.00123 0.0123 0.0246 0.0246 0.01107
