The question is incomplete, here is the complete question:

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 500 mL flask with 4.8 atm of ammonia gas and 1.9 atm of oxygen gas at 33 degress Celsius.

He then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of nitrogen gas to be 0.63 atm. Calculate the pressure equilibrium constant for the combustion of ammonia at the final temperature of the mixture.

The value of pressure equilibrium constant for the given reaction is 0.132

Explanation:

We are given:

Initial partial pressure of ammonia gas = 4.8 atm

Initial partial pressure of oxygen gas = 1.9 atm

Equilibrium partial pressure of nitrogen gas = 0.63 atm

The chemical equation for the reaction of ammonia and oxygen gas follows:

Initial:          4.8           1.9

At eqllm:   4.8-4x     1.9-3x           2x          6x

Evaluating the value of 'x'

So, equilibrium partial pressure of ammonia gas = (4.8 - 4x) = [4.8 - 4(0.315)] = 3.54 atm

Equilibrium partial pressure of oxygen gas = (1.9 - 3x) = [1.9 - 3(0.315)] = 0.955 atm

Equilibrium partial pressure of water vapor = 6x = (6 × 0.315) = 1.89 atm

The expression of for above equation follows:

Putting values in above equation, we get:

Hence, the value of pressure equilibrium constant for the given reaction is 0.132
