Chapter 5, Problem 5.64E

Interpretation Introduction

Interpretation:

The graph of $\Delta G$ (substances), $\Delta G$ (mixing), and the sum of the two $\Delta G$ values for the given reaction is to be plotted. The value of $\xi$ is to be stated.

Concept introduction:

The $\xi$ represents the extent of reaction that is the quantity by how much the reaction has proceeded. It has the unit of moles. It is expressed in terms of any component of reaction. It is given by the relation written as follows.

$\xi =\frac{n_i-n_{i,0}}{v_i}$

In the above equation, $n_i$ is the number of moles of component after the reaction has started, $n_{i,0}$ is the number of moles of the component at $t=0$ and $v_i$ is the difference in number of components at product and reactant side.
