The oxidation of o-dianisidine (o-DIA) occurs in a nernstian 2e reaction. For a 2.27 mM alution of o-DIA in 2 M H2S04 at a carbon paste electrode of area 2.73 mm" with a scan rate of 0.500 V/min. ip = 8.19 uA. Calculate the D value for o-DIA. What ip is expected for v = 100 v/s) What ip wil be obtained for v = 50 mV/s and 8.2 mM o-DlA
