โœฆ Synopsis

Rates of reaction for the alkaline hydrolysis of various hydroxamic acids in the presence of cetyltrimethylammonium bromide have been determined. Empirical reaction orders of zero, one-half, and one were found for the hydroxamic acids depending upon reaction conditions and substrate structure. N-methylhydroxamic acids exhibited only first-order kinetics. The results are consistent with the Michaelis-Menten rate equation.

The Michaelis-Menten formalism assumes that the elementary steps of an enzymatic mechanism follow traditional mass-action kinetics. Recent evidence has shown that elementary bimolecular reactions under dimensionally-restricted conditions, such as those that might occur in vivo when reactions are con
