Abstract

Summary The rates of reaction of nine different a-halogen acids and a-halogen acyl peptides with an excess of ammonia have been measured and the first order constants determined. The reactions have been shown to be bimolecular because the first order constants are proportional to the partial pressures of ammonia in equilibrium with the solutions. The heats and entropies of activation have been calculated for the reactions ...
