Question

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 (03) in the air.
An atmospheric scientist decides to study the reaction between nitrogen dioxide and oxygen that produces dinitrogen pentoxide. He fills a stainless steel reaction
chamber with 5.5 atm of nitrogen dioxide gas and 7.1 atm of oxygen gas and raises the temperature considerably. At equilibrium he measures the mole fraction
of dinitrogen pentoxide to be 0.15.
Calculate the pressure equilibrium constant K. for the equilibrium between nitrogen dioxide, oxygen, and dinitrogen pentoxide at the final temperature of the
P
mixture.
Round your answer to 2 significant digits.
K₁ = 0
