Solution: A sample of pure carbon dioxide at 500 K undergoes spontaneous decomposition to produce the following reaction:2 CO2 (g) ⇌ 2 CO (g)  +  O2 (g)The equilibrium constant KP is 215. Through the reaction it is shown that the partial pressure of O2 is 0.30 at equilibrium. Calculate the partial pressures of CO and CO2 

Problem

A sample of pure carbon dioxide at 500 K undergoes spontaneous decomposition to produce the following reaction:

2 CO2 (g) ⇌ 2 CO (g)  +  O2 (g)

The equilibrium constant KP is 215. Through the reaction it is shown that the partial pressure of O2 is 0.30 at equilibrium. Calculate the partial pressures of CO and CO2
