Chapter 15, Problem 15.119QP

Interpretation Introduction

Interpretation:

The equilibrium constant (Kp), decomposition and mole fractions values should be calculated given the CuO into Cu₂O decomposition reaction with respective temperature at ${1024}^{\text{0}}\text{C}$.

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.

Equilibrium pressure: 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.

Thermal decomposition reaction: This reaction caused by heat or decomposition of starting substance is the temperature at which the substance chemically decomposes. In other words large molecules being broken down into single elements (or) compounds.

Mole fraction: It defined to be equal to the number of moles of a component divided by the total number of moles of solution.

To find: Calculate the partial pressure (Kp) and decomposition values of given ( $\text{CuO}$) decomposition reaction.
