Chapter 13, Problem 87A

Interpretation Introduction

(a)

Interpretation:

The volume ratio of carbon monoxide to carbon dioxide is to be calculated.

Concept introduction:

Stoichiometry concerns are used for it.

Answer to Problem 87A

$\begin{array}{c}\mathrm{Volume}ratioofCOandC{O}_2=2:2\\ =1:1\end{array}$

Explanation of Solution

Volume ratios are calculated by first balancing the reaction then using coefficients of reactant and product as volume equivalents.

Interpretation Introduction

(b)

Interpretation:

The volume of nitrogen required in the reaction of $42.7gCO$ needs to be determined.

Concept introduction:

Stoichiometry of the reaction is used to calculate the result.

Answer to Problem 87A

$17.08L{N}_{2}isproducedby42.7gCO$

Explanation of Solution

The given question involves the chemical equation as:

$2CO+2NO\to N_2+2C{O}_2$

Atomic mass of CO=28 g/mol

According to Avogadro’s principle,

$2\times 28g=56gCOwillproduce22.4L{N}_{2}atSTP$

Now, $\begin{array}{l}42.7gCOwillproduce17.08L{N}_2\left(\frac{22.4}{56}\times 42.7\right)atSTP\end{array}$

Conclusion

$42.7gCOproduce17.08L{N}_2$
