Textbook Problem

Nitrogen dioxide can decompose to nitrogen oxide and oxygen.

2 NO 2 ( g ) 2 NO ( g ) + O 2 ( g )

K is 0.87 at a certain temperature. A 5.0-L flask at equilibrium is determined to have a total pressure of 1.25 atm and oxygen to have a partial pressure of 0.515 atm. Calculate PNO and PNO2 at equilibrium.

Interpretation Introduction

Interpretation:

The partial pressure of NO2 and NO gas at equilibrium needs to be calculated.

Concept introduction:

For a general equilibrium reaction as follows:

A(g)+B(g)C(g)+D(g)

The expression for the equilibrium constant is represented as follows:

K=(PC)(PD)(PA)(PB)

Here, to calculate the equilibrium constant, the values of partial pressure of all the species in reactant and product side are required.

Explanation

The equilibrium reaction is as follows:

2NO2(g)2NO(g)+O2(g)

The expression for the equilibrium constant of the reaction will be:

K=(PO2)(PNO)2(PNO2)2

The equilibrium constant of the reaction is 0.87 and the partial pressure of oxygen gas is 0.515 atm.

Thus,

0.87=(0.515)(PNO)2(PNO2)2

Or,

0.870.515=(PNO)2(PNO2)2

Or,

PNOPNO2=1
