20. The Brusselator. This hypothetical system was first proposed by a group work-
ing in Brussels [see Prigogine and Lefever (1968)] in connection with spatially
nonuniform chemical patterns. Because certain steps involve trimolecular reac
tions, it is not a model of any real chemical system but rather a prototype that
has been studied extensively. The reaction steps are
A-X.
B+X-Y+D.
2X+ Y-3X,
X-E.
305
It is assumed that concentrations of A, B, D, and E are kept artificially con
stant so that only X and Y vary with time.
(a) Show that if all rate constants are chosen appropriately, the equations de
scribing a Brusselator are:
dt
A-(B+ 1)x + x²y,
dy
=Bx-x²y.
