Chapter 15, Problem 15.89SP

Interpretation Introduction

(a)

Interpretation:

The value of ${\text{Q}}_{\text{p}}$ needs to be determined. The direction of reaction in order to reach the equilibrium needs to be determined.

Concept introduction:

In chemical thermodynamics, the reaction quotient ${\text{Q}}_{\text{p}}$ is the ratio of concentration of product to reactant at any point before the equilibrium is reached.

Interpretation Introduction

(b)

Interpretation:

Theequilibrium partial pressure of all the gases needs to be determined.

Concept introduction:

The partial pressure of the reaction is the expression of the equilibrium constant that can be calculated by the partial pressure of gases in the reaction and can be expressed as the ratio of partial pressure of product to reactant.
