The paper deals with the numerical solution of differential equations describing some chemical reactions of dissociation and re-combination. The physical problem and the corresponding equations are presented; one deals with the analytical solution of a first-order approximation with respect to small parameter; and then one considers the same problem for a regular singular perturbation scheme, with slowly varying variables. Numerical results are obtained by using the concepts of fast and slow variables.
