Kinetics Decomposition of Some Substituted Benzendiazonium Salts in HCl Solution.

Abstract

The 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.
