Abstract

Oxidation kinetics of the reaction between NO and sulphites of sodium, potassium, ammonium and calcium were carried out in a stirred cell with a flat interface. The temperature was varied in the range of 30-60°C. The NO partial pressure ranged from 0.05 to 1 kN/m2. The reaction between sulphites and nitric oxides was a fast pseudo second-order reaction. The order in Na2SO3,K3SO3 and (NH4)2SO3 was found to be zero whereas the order in NO was found to be 2 in all cases. The values of activation energy have been reported.
