Chapter 6, Problem 36E

At a particular temperature, 8.0 moles of ${\text{NO}}_{\text{2}}$ is placedinto a 1.0-L container and the ${\text{NO}}_{\text{2}}$ dissociates by thereaction

${\text{2NO}}_{\text{3}}\text{(}g)\rightleftharpoons {\text{2NO}}_{\text{2}}\text{(}g{\text{)+O}}_{\text{2}}\text{(}g\text{)}$

At equilibrium the concentration of NO(g) is 2.0 M.Calculate K for this reaction.
