Chemical kinetics is a branch of chemistry concerned with the velocity of chemical reaction and the mechanism by which chemical occur. It deals with the rates of chemical reactions and how rates depend on factors such as concentration and temperatures. The kinetic study of benzaldehydes has been studied in binary solvent mixtures of water and chromic acid with isoquinolinium bromochromate in the presence of acetic acid at 35-55℃ range of temperature. The oxidation follows first order kinetics with respect to oxidant and [H+] and fractional-order dependence on substrates. The benzoic acid was identified as end-product by existing standard methods. The various thermodynamic parameters were evaluated. The rate laws in constant with the observed kinetic results have been discussed. This work can better and suitably be utilized in medical science by study of drug action, pharmacodynamic etc.
