Kinetics Decomposition of Some Substituted Benzendiazonium Salts in HCl Solution.


AbstractThe decomposition rate, rat constant and decomposition activation energy of substituted benzendiazonium salts ( N+ ≡ NCl-) were calculated by folloing the quantity of nitrogen gas produced as a function of time at several temperatures ranging from (35 to 50)oC. The effect of the R group type on the rate of decomposition ,rat constant and activation energy, was studied. The effect of variation of R group position (o, p, m) has been studied as well.
