Exercise 8 | Chemical Equilibrium

C (s) + CO(g)  2 CO (g)     [KP = 1.00 atm]


Is the reaction at equilibrium if PCO2 = 0.200 bar and PCO = 0.650 bar?

If not, in what direction will the reaction proceed to attain equilibrium?

Let’s calculate the reaction quotient QC:

QC = PCO2PCO2 

Q= 2.11 bar = 1.97 atm


QC > KP

⇒ the reaction is not at the equilibrium

⇒ the reaction will move to the left
