Majority of the literature on development of solutions for rate of absorption accompanied by a single irreversible (1,1) order gas liquid reaction in different regimes was based on classifying different possible simplified regimes of absorption based on assumed concentration profiles of the dissolved gas phase species and a non volatile liquid phase reactant in the liquid film, and developing solutions for the diffusion-reaction model, and giving inequality criteria for the validity of the assumed concentration profiles of the two reactants. The final calculation of rate of absorption was linked to a trial and error method to evaluate the role of gas film resistance. In the present work, a general solution of the film model for mass transfer accompanied by an irreversible (1,1) order gas-liquid reaction taking place in film and bulk which takes into account the depletion of the liquid phase reactant concentration in the liquid film , as well as the role of the gas film resistance is developed by using the Hikita Asai approximation. The criteria for the applicability of various regimes are developed which incorporate the role of the gas film resistance and the corresponding expressions for the rate equation are also derived. The application of these criteria to establish the regime or regimes in which an ideal gas liquid reactor may be operating for a set of given operating conditions or design parameters is discussed.
