Chapter 15, Problem 71AP

Interpretation Introduction

Interpretation:

The equilibrium constant for the reaction is to be determined. A mixture of hydrogen and oxygen gases can be kept at room temperature without any change: this fact is to be explained.

Concept introduction:

Equilibrium is the condition of a chemical system in which the amount of reactants consumed and products formed are equal.

Equilibrium constant of a chemical reaction is defined as the value of reaction quotient when the reaction is in chemical equilibrium.

${\text{K}}_{\text{p}}$ is the equilibrium constant calculated from the partial pressures of a reaction. It plays a key role in expressing the relationship between product pressures and reactant pressures.

The relation between ${\text{K}}_{\text{p}}$ and ${\text{K}}_{\text{c}}$ is:

$K_P=K_C{\left(0.0821\times T\right)}^{\Delta n}$

Here, $\text{T}$ is absolute temperature and $\Delta n$ is difference between the number of moles of product gases and the number of moles of reactant gases.
