The kinetics of the oxidation of oxyhaemoglobin by sodium nitrite has been studied spectrophotometrically. The reaction has been shown to be second order with specific reaction rate of 4.2 x 101 M-1s-1 at 25.0oC and at pH 6.80(Phosphate buffer). The energy of activation, frequency factor and entropy of activation are found to be 57.94 kJM-1, 5.994 x 1011 s-1 and -27.68 JK-1mol-1 respectively. In order to probe inside the mechanism, the effect of ionic strength is also investigated. The most likely mechanism is suggested for the reaction.
