Chapter 5.4, Problem 5.13BFP

Interpretation Introduction

Interpretation:

The volume of gaseous iodine pentafluoride measured $105\text{°C}$ and $0.935\text{atm}$ prepared by the reaction of $4.16\text{g}$ of solid iodine with $2.48\text{L}$ of gaseous fluorine at $18°\text{C}$ and $0.974\text{atm}$ is to be calculated.

Concept introduction:

Ideal gas law equation is as follows:

$PV=nRT$ (1)

Here,

$P$ is the pressure of the gas.

$V$ is the volume occupied by 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)

When the number of each atom in the reactant side is equal toa number of each atom in the product side then the reaction is known as a balanced chemical reaction. The reactant present in the lower quantity of moles is the limiting reagent.
