Chapter 17, Problem 17.31E
Interpretation Introduction

(a)

Interpretation:

The energy A or G having the higher absolute value is to be predicted on the basis of statistical thermodynamic definitions.

Concept introduction:

Gibbs free energy gives the value of the maximum reversible amount of work done by system at a condition of constant temperature and pressure. It is a state function.

Helmholtz energy gives the value of the maximum amount of work done by system at a condition of constant volume. It is a state function.

Interpretation Introduction

(b)

Interpretation:

The energy E or G having the higher absolute value is to predicted on the basis of statistical thermodynamic definitions and the reason for the same is to be stated.

Concept introduction:

Internal energy is defined as the total energy contained in a system. Its absolute value cannot be measured directly. It is a state function.

Gibbs free energy gives the value of the maximum reversible amount of work done by system at a condition of constant temperature and pressure. It is a state function.

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. di
