Chapter 12, Problem 17QAP

Interpretation Introduction

Interpretation:

The value of equilibrium constant for the given reaction needs to be determined.

Concept introduction:

The system is said to be in equilibrium if the there is no change in the partial pressure or concentration of reactant and product takes place.

For a general reaction as follows:

$\text{A}\left(g\right)+\text{B}\left(g\right)\rightleftharpoons \text{C}\left(g\right)+\text{D}\left(g\right)$

The expression for the equilibrium constant is represented as follows:

$K=\frac{\left(P_C\right)\left(P_D\right)}{\left(P_A\right)\left(P_B\right)}$

Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.

If an equilibrium reaction is reversed, the value of its equilibrium constant gets inversed. If an equilibrium reaction is multiplied by any value, the value will become the power of the equilibrium constant. On adding two equilibrium reactions, the value of their equilibrium constant gets multiplied. On subtracting two equilibrium reactions, the value of their equilibrium constant gets divided.
