Using a perpetual change curve, the ratio of [Cu2+]/[o-phen] was found to be 1 : 1 The rate equations perpetual change curve demonstrates that one molecule of OPDA reacts with one Cu2+ ion and a monoimine is formed as the transfer of one electron occurs in the oxidation reaction.en10.1081/CI-120018403info:eu-repo/semantics/closedAccessO-Phenylenediamine (OPDA)Reaction KineticsOxidation Of O-PhenylenediamineCopper (II)Article3111521Q2WOS:0001814228000022-s2.0-0037300668Q3
