Chapter 5, Problem 5.49E

(a)

Interpretation Introduction

Interpretation:

The equilibrium concentration are $\text{0}\text{.405 mol}\cdot {\text{L}}^{\text{-1}}{\text{ N}}_{\text{2}}{\text{O}}_{\text{4}}\text{ and 2}\text{.13 mol}\cdot {\text{L}}^{\text{-1}}{\text{ NO}}_{\text{2}}$, K of the reaction has to be calculated.

(b)

Interpretation Introduction

Interpretation:

When adding $1.00molN{O}_{2}isaddedto1.00L$ of the solution and the system is allowed to reach equilibrium again at the same temperature, the direction of the reaction has to be explained.

(c)

Interpretation Introduction

Interpretation:

To prove the prediction of part (b), after adding $N{O}_2$, the final equilibrium concentration has be calculated.
