Chapter ER, Problem 30PQ
Interpretation Introduction

Interpretation:

The change which produces most positive voltage change in the given half cell reaction has to be given.

Concept Introduction:

The Nernst equation is,

  E(cell)=Eo(cell)-RTnFlnQ

Where,

  • E(cell) is the reduction potential at the current conditions.
  • Eo(cell) is the standard reduction potential relative to hydrogen  reduction potential at 25oC.
  • R is the universal gas constant.
  • T is the temperature in K
  • n is the moles of electrons transferred between the positive and negative terminals of the electrochemical system.
  • F is Faraday's constant.
  • Q is the Reaction Quotient.

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
