(b) A reductive current is passed through an aqueous solution of methyl viologen dication to effect the reaction MV2++ee+MV+. The optical absorbance at 600nm(max for the radical cation MV+ ) increased by 1.200AU. The pathlength l is 1cm and the extinction coefficient E for the radical in water is 13300cm1mol1dm3. Calculate the molar concentration of the radical that was formed
