Chapter 8, Problem 8.58SP

Interpretation Introduction

Interpretation:

$\Delta E$ for the reaction of ethylene with $H_2$ has to be calculated.

Concept Introduction:

• According to First law of Thermodynamics, work done is given by,

$w=-P\Delta V$

Where,

$\begin{array}{l}P=\text{ pressu}re\\ \Delta V=\text{ change in volume}\end{array}$

• Enthalpy corresponds to heat content of the system and it is represented by ‘H’ and it is the sum of internal energy ‘E’ and product of volume and pressure,

$H=E+PV$
