##### Abstract:

AbstractFor gas absorption accompanied by (m,n)-(p,q)-th order reversible, consecutive and parallel chemical reactions, the approximate solutions based on the penetration and surface renewal theories are derived under the condition of equal diffusivities, and compared with the approximate solution based on the film theory to manifest the generalized solution being suitable for three theories. For the case of reversible chemical reaction, the approximate solution based on the penetration theory is compared with the numerical solution to examine the accuracy of Hikita and Asai's approximation in the unsteady state. It is found that the division of the approximate solution from the numerical solution is only a few per cent.
