Chapter 7, Problem 116IAE

Interpretation Introduction

Interpretation:

The value of $\Delta h$ for the conversion of one mole of washing soda into soda ash needs to be determined. The value of $\Delta U$ for this process needs to be determined and this is to be explained why it is only an estimate.

Concept introduction:

The relation between $\Delta U$ and $\Delta H$ is represented as follows:

$\Delta U=\Delta H-P\Delta V$

Here, $\Delta U$ is internal energy, $\Delta H$ is enthalpy, P is pressure and $\Delta V$ is change in volume.
