If we Consider a reversible reaction: aA + bB ⇌ cC + dD
Then the equilibrium constant (Kc) for the reaction expressed in
terms of the concentration (mol / litre) may be expressed as:
K c = [C] c [D] d / [A] a
[B] b
where a, b, c, d are the number of moles of each reacctant and product involved in the reaction
[C] ,[D] , [A], [B] are the concentration of products and reacctants respectively at equilibrium
The calculated concentration of NO2 at equilibrium is 0.0152 M
