To calculate the concentration of [12], use Equation (3) and the concentration of [S₂03²]. In a constant-temperature run described in the procedure section of this experiment, the solution turned blue in 50 s. a) Consider the concentration of [S₂032] in the mixed solution shown in the las column of the table from the previous exercise. Calculate the concentration c [12] final formed in this reaction. b) Calculate the rate of the reaction.
