Chapter 16, Problem 176AP

Interpretation Introduction

Interpretation:

The degree of dissociation of dimer and the equilibrium concentration $\left(K_p\right)$ at the particular temperature and pressure are to be calculated.

Concept Introduction:

An ideal gas can be characterized by three state variables, namely absolute pressure $\left(P\right)$, volume, and absolute temperature $\left(T\right)$. The relation between them that may be reduced from kinetic theory is called the ideal gas equation.

The ideal gas equation is as follows:

$PV=n\text{R}T.$

Here, $V$ is the volume, $n$ is the number of moles, $R$ is the universal gas constant, $P$ is the pressure of the gas, and $T$ is the temperature of the gas.

The number of moles of a solute divided by the number of litres of solution is called molarity.

The number moles of NaOH reacted with a dimer of acetic acid using the molarity is as follows:

$Molarity=\frac{Moles}{Volume}.$

The moles of the dimer are calculated as follows:

$\text{Moles of dimer}=\frac{Moles\text{ of NaOH}}{2}$.
