Resumos Cadastrados

Resumo Inglês:

The oxidation of niacinamide in alkaline media is carried out using potassium permanganate as an oxidizing agent. The reaction was monitored using UVVisible spectrophotometer at 525 nm. It was found to be zero order with respect to oxidant, fractional order with respect to hydrogen ion concentration and first order with respect to substrate. The thermodynamic parameters were determined. The average (ΔG#) was found to be 87.60 KJ/mol. The values ΔS# was found to be -0.2132 KJ/mole and energy of activation was found to be 23.95 KJ/mole. A suitable mechanism is proposed based on the experimental conditions.
