Adding more gas C to the system would shift the equilibrium system to the left.
<h3>What is a chemical balance?</h3>
In a chemical reaction, there is an equilibrium determined by several factors, such as mole concentration, increase or decrease in temperature and addition of mass.
When the amount of reactants is increased, the reaction favors the side of the products and vice versa.
So, to shift the equilibrium to the left, that is, to the reactant side, more of the gas C must be added.
