Aspectrophotometry experiment was conducted for the following reaction, which occurred in a 1.10 cm cuvette. the initial concentration of the blue reaciton was 0.75a(aq) (colorless)+b(aq) (blue)→c(aq) (colorless)+d(aq) (colorless)absorbance, a time, t 0.77 0.00s 0.67 30.00s 0.60 60.00sa. find the molar absorptivity coefficient, a, for the blue reactant. b. find the initial rate of the reaction.
