According to Le Chatelier's principle, if the concentration of a reactant is increased in a system at equilibrium, the system will adjust to counteract that change. In this case, increasing the concentration of CO will shift the equilibrium to the right to produce more products (CO2) in order to reduce the concentration of CO.

Therefore, the correct answer is:
3. to the right.
