Chapter 11.1, Problem 6SSC

Interpretation Introduction

Interpretation:

The number of mole ratios that can be written for a reaction involving three substances is to be stated.

Concept introduction:

Mole ratio is use for the conversion between products and reactants. It is defined as the ratio of moles of any of the two compounds that are involved in the reaction.

Answer to Problem 6SSC

The mole ratio for equation having three substances is shown below:

$\begin{array}{l}x\text{A}/y\text{B}\text{and}\text{}x\text{A}/z\text{AB}\\ y\text{B}/x\text{A}\text{and}\text{}y\text{B}/z\text{AB}\\ z\text{AB}/x\text{A}\text{and}\text{}z\text{AB}/y\text{B}\end{array}$

Explanation of Solution

The example of chemical equation having three substances is shown below:

$x\text{A}+y\text{B}\to z\text{AB}$

The first mole ratio for above equation is shown below:

$x\text{A}/y\text{B}\text{and}\text{}x\text{A}/z\text{AB}$

Thus, on reaction of x moles of A, y moles of B are used. Similarly, on reaction of x moles of A, z moles of AB are formed.

The second mole ratio for above equation is shown below:

$y\text{B}/x\text{A}\text{and}\text{}y\text{B}/z\text{AB}$

Thus, on reaction of y moles of B, x moles of A are used. Similarly, on reaction of y moles of B, z moles of AB are formed.

The third mole ratio for above equation is shown below:

$z\text{AB}/x\text{A}\text{and}\text{}z\text{AB}/y\text{B}$

Thus, on formation of z moles of AB, x moles of A are used. Similarly, on formation of z moles of AB, y moles of B are used.

Conclusion

The mole ratio for equation having three substances is shown below:

$\begin{array}{l}x\text{A}/y\text{B}\text{and}\text{}x\text{A}/z\text{AB}\\ y\text{B}/x\text{A}\text{and}\text{}y\text{B}/z\text{AB}\\ z\text{AB}/x\text{A}\text{and}\text{}z\text{AB}/y\text{B}\end{array}$
