Nitrogen forms a surprising number of compounds with oxygen. A number of these, often given the collective symbol

NOx

(for "nitrogen +

x

oxygens") are serious contributors to air pollution. They can often be interconverted, sometimes by reaction with oxygen or ozone (

O3

) in the air.

An atmospheric scientist decides to study the reaction between nitrogen monoxide and oxygen that produces nitrogen dioxide. He fills a stainless steel reaction chamber with

1.7atm

of nitrogen monoxide gas and

2.0atm

of oxygen gas and raises the temperature considerably. At equilibrium he measures the mole fraction of nitrogen dioxide to be

0.54

.

Calculate the pressure equilibrium constant

Kp

for the equilibrium between nitrogen monoxide, oxygen, and nitrogen dioxide at the final temperature of the mixture.
