Chapter 15, Problem 80IAE

A sample of a with a mole ratio of ${\text{N}}_2$ to ${\text{O}}_{\text{2}}$ , of 79.21 is heated so 2500 K When equilibrium is established in a closed container with air initially at 1.00 atm, the mole percent of NO — Sound to b 18%. Calculate ${\text{K}}_C$, for reaction below, assuming pressures are expressed in atmospheres.

${\text{N}}_{\text{2}}\left(\text{g}\right){\text{+O}}_{\text{2}}\left(\text{g}\right)\rightleftharpoons \text{2NO}\left(\text{g}\right)$
