Question
Chapter 9, Problem 13QAP
Interpretation Introduction
Interpretation:
The vapor pressure of octane is obtained by the following data-
| Vp(mmHg) | 10 | 40 | 100 | 400 |
| t (°C) | 19.2 | 45.1 | 65.7 | 104.0 |
The graph between ln(vp) and 1/T is to be plotted. The heat of vaporization of octane is to be estimated by this graph.
Concept introduction:
The relation between pressure, temperature and change in enthalpy of vaporization is as follows:
Here,
P = pressure
T = temperature
A = y-intercept from the graph.

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,
