If the rate of the reaction A + B rightarrow C + D is measured by determining the time for the concentration of A to decrease by 2.0 times 10^-3 mol/L, calculate the reaction time (sec) when the rate is 4.0 times 10^-5 mol/L-sec. Calculate the initial concentrations of I^- and S_2O_8^2- in each of the reaction mixtures in Table 1. For example, the concentration of I^- in mixture 1 is: 0.200 mol/L times 0.0200 L/0.0510 L = 0.0784 mol/L...
