Interpretation Introduction

Interpretation:

The equilibrium constant (Kp) value should be calculated given the ozone (O₃) into oxygen (O₂) equilibrium reaction at 25⁰C.

Concept Introduction:

Equilibrium constant: Concentration of the products to the respective molar concentration of reactants it is called equilibrium constant. If the K value is less than one the reaction will move to the left side and the K values is higher (or) greater than one the reaction will move to the right side of reaction.

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.

Standard free energy $({\text{ΔG}}_{\text{f}}^{\text{0}})$: This thermodynamic function associated with a chemical reaction that can be used to do work. The standard free energy of formation of a compound change of Gibbs free energy the formation of 1 mole of substance from its component elements, at their standard states (For example the obtained product is more stable at 25⁰C).

Homogeneous equilibrium: A homogeneous equilibrium involved has a everything present in the same phase and same conditions, for example reactions where everything is a gas, or everything is present in the same solution.

To find: Calculate the entropy values $({\text{ΔG}}^0)$ for given the statement.
