Chapter 15, Problem 15.153QP

Interpretation Introduction

Interpretation:

The partial pressure values $(\pm \Delta n)$ are should be calculated given the heterogeneous equilibrium reactions with supporting of thermodynamic equation.

Concept Introduction:

Chemical equilibrium: The term applied to reversible chemical reactions. It is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. The equilibrium is achieved; the concentrations of reactant and products become constant.

Heterogeneous equilibrium: This equilibrium reaction does not depend on the amounts of pure solid and liquid present, in other words heterogeneous equilibrium, substances are in different phases.

Partial pressure (Kp):  The equilibrium constant calculated from the partial pressures of a reaction equation. It is used to express the relationship between product pressures and reactant pressures. It is unites number, although it relates the pressures.
