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 6.1 atm of nitrogen monoxide gas and 5.2 atm of oxygen gas and raises the temperature considerably. At equilibrium he measures the mole fraction of dinitrogen pentoxide to be 0.37. Calculate the pressure equilibrium constant Kp for the equilibrium between nitrogen dioxide, oxygen, and dinitrogen pentoxide at the final temperature of the mixture. Round your answer to 2 significant digits.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
