Chapter 15.4, Problem 15.4.3SR

Interpretation Introduction

Interpretation:

The equilibrium constant (Kp) values should be calculate given the ammonia (NH₃) formation reaction with supporting from Standard state free energy $({\text{ΔG}}^0)$ values.

Concept Introduction:

Free energy $(\text{ΔG})$: It is a thermodynamic free energy is the amount of work that a thermodynamic system can performed. Moreover the free energy is the internal energy is a system minutes the amount of energy that cannot be used to perform work.

Standard state free energy $({\text{ΔG}}^0)$: The standard Gibbs free energy of formation of a compound in the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its respective component elements and their standard states. In other words the most stable compounds at 25⁰C and 100 k/ Pascal’s this symbol denoted by $({\text{Δ}}_{\text{f}}{\text{G}}^0)$.

Equilibrium 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.
