Abstract

The kinetics of resorcinol inhibited CoO catalysed S(IV) autoxidation in the pH range 7.50 to 8.50 medium have been investigated and a rate law & free radical mechanism have been proposed based on the observed results and inhibition parameters. In all situations, the reaction's order and rate constants were calculated, meanwhile, the reaction was determined to be first-order. The impact of various temperatures & pH levels were explored also. We reported resorcinol as a significant inhibitor for SO2 autoxidation in the pH range of 7.50 to 8.80. The Arrhenius equation was used to get the value of apparent activation energy (Ea) (K= A.e-Ea/RT).
