Chemistry Dept, Faculty of Science, Ain Shams University, Abbassia, Cairo, Egypt.

Abstract

The rate of reaction of Mn NTMP with H₂O₂ in KNO₃ solution was investigated at various temperatures, and pH's

The general rate quation is

[Math] [Complex] [H₂O₂]

Values of k₁ and K₁ were calculated. The activation enthalpy (ΔH* = 84.0 KJ mol^-1) and activation entropy (ΔS* -6 JK^-1 mol^-1) were calculated from Arrhenius plots.
