The kinetics of the reaction between nitric oxide and chlorine have been investigated in both carbon tetrachloride and glacial acetic acid. The nitric oxide-oxygen reaction has been investigated in carbon tetrachloride.
The appearance of product, NOCl or NO,, was monitored spectrophotometrically a t a wavelength of 475 nm for NOCl and 343 nm for NO,. These measurements were performed using an Amino-Morrow stopped-flow apparatus equipped with a Beckman D U monochromator.
The data for both the NO-Cl, and NO-02 systems could be fitted to the third-order integrated equation and the calculated rate constants were 2.75 x lo3 M 's-' and 2.79 x lofi M -' s ', respectively, at 25.1%.
There was a noted increase in rate constants on changing the solvent from carbon tetrachloride to acetic acid.
The likelihood of a termolecular encounter is inherent in the mechanism, however, no real evidence to substantiate either a direct termolecular or a series of two bimolecular steps has been obtained, although a -7 kcal for AHo would support the latter.

The kinetics of the reaction between nitric acid and formaldehyde have been studied by spectrophotometry. The reaction is autocatalytic. A two-step mechanism is proposed, which accounts for this behavior and describes the effect of reactant concentrations on the characteristics of the kinetic curves
