Chapter 17, Problem 129AE

Interpretation Introduction

Interpretation:

The production of 1,4-dicyanobutane electrochemically and the further reduction of compound for its use in the production of nylon is given. The amount of current used to produce given amount of $\text{NC}-{\left({\text{CH}}_2\right)}_4-\text{CN}$ per hour is to be calculated.

Concept introduction:

The non-spontaneous reaction takes place in an electrolytic cell in which there occurs conversion of electrical energy into chemical energy and this is used for the electrolysis of a metal.

The charge generated in the cell is calculated as,

$Q=It$

When electricity is passed through an electrolytic cell, at that time the amount of the substance that is liberated at an electrode is given by,

$\begin{array}{c}W=ZQ\\ =ZIt\end{array}$

The value of $Z$ is given as,

$Z=\frac{\text{Molar}\text{mass}}{n\times 96,485}$

To determine: The amount of current used to produce given amount of $\text{NC}-{\left({\text{CH}}_2\right)}_4-\text{CN}$ per hour.
