Chapter 8, Problem 8.45E
Interpretation Introduction

(a)

Interpretation:

The reaction equation that corresponds to each of the given equilibrium expression is to be stated.

Concept introduction:

When any reaction is at equilibrium then a constant expresses a relationship between the reactant side and the product side. This constant is known as equilibrium constant. It is denoted by K. The equilibrium constant is independent of the initial amount of the reactant and product.

Answer to Problem 8.45E

The reaction equation that corresponds to given equilibrium expression is 3HF+PF3PH3+3F2.

Explanation of Solution

The value of equilibrium constant is equal to the product of the concentration of the products raised to the power of their stoichiometric coefficient divided by product of the concentration of reactants raised to the power of their stoichiometric coefficient in chemical equation.

The given equilibrium expression is shown below.

K=[PH3][F2]3[HF]3[PF3]

Thus, the coefficient of PH3 is one, F2 is three, HF is three and PF3 is one. The reaction equation is shown below.

3HF+PF3PH3+3F2

Conclusion

The reaction equation that corresponds to given equilibrium expression is 3HF+PF3PH3+3F2.

Answer to Problem 8.45E

The reaction equation that corresponds to given equilibrium expression is 4NO2+6H2O7O2+4NH3.

Explanation of Solution

The value of equilibrium constant is equal to the product of the concentration of the products raised to the power of their stoichiometric coefficient divided by product of the concentration of reactants raised to the power of their stoichiometric coefficient in chemical equation.

The given equilibrium expression is shown below.

K=[O2]7[NH3]4[NO2]4[H2O]6

Thus, the coefficient of O2 is seven, H2O is six, NH3 is four and NO2 is four. The reaction equation is shown below.

4NO2+6H2O7O2+4NH3

Conclusion

The reaction equation that corresponds to given equilibrium expression is 4NO2+6H2O7O2+4NH3.

Answer to Problem 8.45E

The reaction equation that corresponds to given equilibrium expression is 2Cl2O5O2+4ClO2.

Explanation of Solution

The value of equilibrium constant is equal to the product of the concentration of the products raised to the power of their stoichiometric coefficient divided by product of the concentration of reactants raised to the power of their stoichiometric coefficient in chemical equation.

The given equilibrium expression is shown below.

K=[O2][ClO2]4[Cl2O5]2

Thus, the coefficient of O2 is one, ClO2 is four and Cl2O5 is two. The reaction equation is shown below.

2Cl2O5O2+4ClO2

Conclusion

The reaction equation that corresponds to given equilibrium expression is 2Cl2O5O2+4ClO2.

Answer to Problem 8.45E

The reaction equation that corresponds to given equilibrium expression is 2NO+2H2N2+2H2O.

Explanation of Solution

The value of equilibrium constant is equal to the product of the concentration of the products raised to the power of their stoichiometric coefficient divided by product of the concentration of reactants raised to the power of their stoichiometric coefficient in chemical equation.

The given equilibrium expression is shown below.

K=[N2][H2O]2[NO]2[H2]2

Thus, the coefficient of N2 is one, H2O is two, H2 is two and NO is two. The reaction equation is shown below.

2NO+2H2N2+2H2O

Conclusion

The reaction equation that corresponds to given equilibrium expression is 2NO+2H2N2+2H2O.
