A closed-form solution is obtained for the problem of dispersion of solute in a non-isothermal flow of a Newtonian fluid with temperature-dependent viscosity. The effect of wall-catalysed reaction on dispersion is investigated against the background of the no-reaction problem. The analytical result on dispersion of solute with wall catalysed reaction at long times is compared with the analytical solution when reaction is absent. The Taylor (1953) and Aris (1956) regimes of dispersion for the present problem are obtained as limiting cases from the study. The graphical results of the study serve as a jury on any numerical study that might be undertaken considering non-asymptotic all-time analysis. The results of the study indicate that heating from above is an effective means of controlling dispersion in variable-viscosity liquids.
