III. The conditions of the evolution of gases from homo­geneous liquids

Abstract

This paper is conveniently divided into three parts. In part (i) an account is given of the effect of finely divided particles on the rate of evolution of gases resulting from chemical changes ; in part (ii) the phenomenon of initial acceleration, as also the effect of variation of pressure on the evolution of gases, is discussed; in part (iii) the case of the decomposition of formic acid into carbonic oxide and water is investigated under constant conditions, other than those of the mass of reacting substances and of temperature.
