Answer :

The equilibrium to shift as in direction where the drop in concentration of occurs if the concentration of [tex]Co_{2}[/tex]is raised on the product side. As a result, the equilibrium will move to the left.

what is equilibrium?

During a reversible chemical process, chemical equilibrium is the state in which there is no net change in the quantity of reactants or products. The moment the products are produced in a reversible chemical reaction, they begin to interact with the initial reactants.

When the two opposing reactions are in equilibrium, there is no net change in the amount of the chemicals involved since they are taking place at the same rates, or velocities.

However at time, the reaction may be deemed to have finished, meaning that the maximum amount of reactants to products has been converted under the given reaction conditions.
