The reaction is first order with respect to both total chromium(III) and total periodate, and the rate is inversely dependent upon H+ in the 5.43-7.02 pH range. The reaction may follow a two-step inner-sphere electron transfer mechanism. The activated parameters are reported. Steric effects of the phenyl ring account for the smaller electron-transfer rate constants for [CrIIIZ(H2O)] compared to [CrIII(TOH)(H2O)], (TOH=N-(2-hydroxyethyl)ethylenediaminetriacetate).
