Chapter 2, Problem 2E.1ST

Interpretation Introduction

Interpretation:

Enthalpy of vaporization of benzene at its normal boiling point has to be calculated.

Concept Introduction:

Energy transferred $q$ can be calculated by using

$q=IVt$ ; Where $I$ is the current, $V$ is the voltage and $t$ is the time.

The change in enthalpy of a system can be determined as the energy transferred to the system as heat at constant pressure.

  $\Delta H=q$

Where $\text{q}$ is the heat energy absorbed or released, $w$  is the work done to the system or from the system.

The molar enthalpy change is given by $\Delta H=\frac{q_p}{n}$; where $n$ is the number of moles.
