In this article, when a gaseous component is absorbed by a liquid under simultaneous reaction with a component of the liquid, the overall rate of reaction proves to be a dimensionless function of four limiting rates.Abstract:
When a gaseous component is absorbed by a liquid under simultaneous reaction with a component of the liquid, the overall rate of reaction proves to be a dimensionless function of four limiting rates:
a.the maximum rate of diffusion of the gaseous component through the liquid film
b.the maximum rate of diffusion of the liquid-component through the liquid film
c.the limiting rate of reaction within the liquid film (during diffusion)
d.the maximum rate of reaction within the main body of the liquid.
A graphical representation of the theoretical relationship enables one to predict the overall rates of interphase mass exchange under arbitrary conditions, as soon as reaction velocity coefficients and mass transfer coefficients are available.read more

Studies of gas absorption. IV. Simultaneous gas absorption and chemical reaction
TL;DR: In this paper, the authors divided gas absorption with simultaneous chemical reaction into three characteristic groups: moderately rapid and slow reactions, very fast reactions, and very slow reactions with resistance to the solute gas.
