Chapter 6, Problem 6.132QE

Interpretation Introduction

Interpretation:

The change in enthalpy for the reaction of $1{\text{ mol B}}_{\text{2}}{\text{H}}_{\text{6}}$ if the reaction of $2.329{\text{ L B}}_{\text{2}}{\text{H}}_{\text{6}}$ at $\text{744 torr}$ and $\text{120 }°\text{C}$ yields $143.9\text{ kJ}$ heat at constant pressure has to be calculated.

Concept Introduction:

Any gas that obeys the assumption laid down in kinetic molecular theory is said to be an ideal gas. The combination of all the gas laws namely Boyle’s law, Charles law and Avogadro’s leads to the ideal gas equation that can be used to relate all the four properties such as given below:

  $PV=nRT$

Here,

$R$ is universal gas constant.

$V$ denotes the volume.

$n$ denotes the number of moles.

$T$ denotes temperature.

$P$ denotes the pressure.
