to study the effect of reactant concentration on reaction rate is to initial rate depends on the starting concentrations. It is preferable rates because as the reaction proceeds, the concentrations of the and it may become difficult to measure the changes accurately, be a reverse reaction of the type products rightarrow reactants which would introduce error into the rate measurement. Both of these virtually absent during the early stages of the reaction. Table 13.2 shows three rate measurements for the formation of FClO_2. 1 and 3, we see that as we double [F_2] while holding [ClO_2] constant rate doubles. Thus, the rate is directly proportional to [F_2]. Similarly, 1 and 2 shows that as we quadruple [ClO_2] at constant [F_2], the rate
