We study the movement of the center of reaction front in the reaction diffusion system nA + mB → C for arbitrary diffusivities (Da ≠ Db). We present numerical evidence that xf (t) ∝ √t for all t ∈ (0, ∞). Numerical experiments are carried out for (n, m) = (1,1), (1,2), (2,1) and (2,2) and for various $$ \frac{{D_{a} }}{{D_{b} }} $$ D a D b . Finite difference method is used. Empahsis is not on asymptotic behaviour or scaling, rather on verifying the stated claim for all t.
