(a)
Interpretation Introduction
Interpretation:
The structure formula for portion of polymer obtained from orthophthalic acidand glycerol needs to be determined.
Concept Introduction:
A polymer is a long chain molecule made of large number of monomer units. The monomer is repeating units of a polymer that are linked to each other to produce a molecule of polymer.
These monomer units are linked to each other either through the formation of peptide linkage or glycosidic linkage or by removal of any moiety such as a water molecule.
Polyvinyl chloride, Bakelite and polystyrene are some of the example of

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:

A-(B+ 1)x + x²y,
