Chapter 5.4, Problem 5.13AFP

Interpretation Introduction

Interpretation:

The pressure inside the flaks after the reaction in a $10.0\text{ L}$ flask conatining ammonia at $0.452\text{atm}$ and $22°\text{C}$ with $155\text{mL}$ of hydrogen chloride gas at $7.50\text{atm}$ and $271\text{K}$ is completed is to be calculated.

Concept introduction:

Ideal gas law equation is as follows:

$PV=nRT$ (1)

Here,

$P$ is the pressure of gas.

$V$ is the volume occupied by a gas.

$n$ is the number of moles of gas.

$T$ is the temperature in kelvin.

$R$ is the universal gas constant.

Rearrange equation (1) for $n$ as follows:

$n=\frac{PV}{RT}$ (2)

Conversion factor to convert $\text{mL}$ to $\text{L}$ is as follows:

$1\text{mL}={10}^{-3}\text{L}$

The conversion factor to convert $°\text{C}$ to Kelvin is as follows:

$T\left(\text{K}\right)=T\left(\text{°C}\right)+273.15$ (3)

The reactant present in the lower quantity of moles is the limiting reagent.
