Chapter 21, Problem 12E

Interpretation Introduction

Interpretation:

To determine the equilibrium constant for the following reaction below at 298K and also identify whether ${\text{KO}}_{\text{2}}$ is thermodynamically stable with respect to ${\text{K}}_{\text{2}}\text{O}$ and ${\text{O}}_{\text{2}}$ at

298 K or not.

${\text{2KO}}_{\text{2}}\text{(s)}\underset{}{\to }{\text{K}}_{\text{2}}\text{O(s)+}\frac{\text{3}}{\text{2}}{\text{O}}_{\text{2}}\text{(g)}$

Concept introduction:

For a chemical reaction, equilibrium constant refers to the value of reaction quotient at equilibrium. In a chemical reaction under set of reaction conditions, the symbol of equilibrium constant is ‘K’ and it doesn’t depend upon the initial concentrations of the products and reactants.
