Chapter 24, Problem 58IAE

Interpretation Introduction

Interpretation:

The mole fractions of all the species involved in the formation of ${\left[\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\right]}^{2+}$ needs to be determined.

Concept introduction:

A general equilibrium reaction is represented as follows:

$aA+bB\rightleftharpoons cC+dD$

The equilibrium constant expression for the reaction can be written as follows:

$K=\frac{{\left[C\right]}^c{\left[D\right]}^d}{{\left[A\right]}^a{\left[B\right]}^b}$

Here, A, B, C and D are reactant and product species involved in the equilibrium reaction and a, b, c and d are their respective stochiometric coefficients.

The mole fraction of any species in the reaction mixture can be calculated as follows:

$X_{\text{A}}=\frac{n_{\text{A}}}{n_T}$

Here, $n_{\text{A}}$ is number of moles of the species and $n_T$ is total number of moles.
