This is an extension of earlier work in which a linear analysis of hydrodynamic stability was applied to a fluid mixture contained between two horizontal planes. One species diffuses to the lower plane where it is destroyed by a rapid exothermic or endothermic catalytic reaction. In the present work, Galerkin's method has been used to study the importance of oscillatory instability in a system with the more dense species concentrated near the top plane. Results show that, for cases likely to be of physical interest, oscillatory instabilities are not expected.
