Chapter 13, Problem 84A

Interpretation Introduction

Interpretation: The volume of ammonia produced by $13.7\text{L}$ hydrogen gas needs to be determined.

Concept introduction: It involves stoichiometry of the reaction and Avogadro’s law.

Answer to Problem 84A

The volume of ammonia produced is $9.13\text{L}\text{N}{\text{H}}_3$ .

Explanation of Solution

The given equation is:

  ${\text{N}}_2+3{\text{H}}_2\to 2\text{N}{\text{H}}_3$

Equation shows $3\text{L}$ of hydrogen forms $2\text{L}\text{N}{\text{H}}_3$ .

Therefore $13.7\text{L}{\text{H}}_2$ will be form ammonia:

  $\begin{array}{c}13.7\text{L}{\text{H}}_2=13.7\text{L}{\text{H}}_2\times \frac{2\text{L}\text{N}{\text{H}}_3}{3\text{L}{\text{H}}_2}\end{array}$

       $\begin{array}{c}=9.13\text{L}\text{N}{\text{H}}_3\end{array}$

Conclusion

$9.13\text{L}\text{N}{\text{H}}_3$ is produced by $13.7\text{L}$ hydrogen gas.
