Abstract Absorption with first order chemical reaction into a liquid film in laminar flow was analysed for the cases of zero and finite resistance in the gas phase. The result was obtained in terms of a sum of a hyperbolic function and an infinite series of hypergeometric functions. The one or two parameters entering the solution contain the rate constant and the mass transfer coefficient in the gas phase, respectively. Ten eigenvalues and integration constants were calculated for several values of the reaction rate parameter for the simpler case of no resistance in the gas phase. The analysis of the results showed that the length of the entrance region can vary substantially depending on the reaction rate constant.
