The equilibrium constant for the reaction is 42 1014 The molar absorptivities for the two principal species in a solution of K2Cr2O2 are Four solutions were prepared by dissolving

The equilibrium constant for the reaction

is 4.2 X 1014. The molar absorptivities for the two principal species in a solution of K2Cr2O2 are

Four solutions were prepared by dissolving 4.00 × 10-4. 3.00 × 10-4. 2.00×10-4 and 1.00 x 10-4 moles of K2Cr2O2 in water and diluting to 1.00 L with a pH 5.60 buffer. Derive theoretical absorbance values (1.00-cm cells) for each solution and plot the data for (a) 345 nm, (b) 370 nm. and (c) 400 nm.
