Explanation:
Hello,
In this case, for the given chemical reaction at equilibrium:
The initial concentration of sulfur trioxide is:
Hence, the law of mass action to compute Kc results:
In such a way, in terms of the change due to the reaction extent, by using the ICE method, it is modified as:
In that case, as at equilibrium 0.11 moles of oxygen are present, equals:
Therefore, the equilibrium constant finally turns out:
