Chapter 6, Problem 6.67QE

Interpretation Introduction

Interpretation:

The volume of hydrogen gas required to react with $\text{4}\text{.2 L}$ of ${\text{N}}_2$ has to be calculated.

Concept Introduction:

Avogadro’s gaseous law states that for an ideal gas, volume varies directly with the number of moles of the gas, provided pressure and temperature remain constant. Mathematically, the relationship between volume and number of moles that holds true is given as follows:

  $\frac{V}{n}=\text{constant}$

The consequence of this law is that it allows equal volume to contain same number of moles provided temperature and pressure are maintained constant. Therefore the same coefficients that represent the number of moles also represent the volume of each reactant that reacts to form a particular product.
