In which direction will the chemical equilibrium of the reaction shift, the equation of which is 2CO + O2 = 2CO2

In which direction will the chemical equilibrium of the reaction shift, the equation of which is 2CO + O2 = 2CO2 + Q, in the case of: 1) An increase in the concentration of O2? 2) Catalyst Applications?

The chemical equilibrium of the system can be shifted by changing three parameters: temperature, pressure and concentration of substances before or after the reaction. The equilibrium system must return to the equilibrium state again. This is a state in which how many molecules of carbon dioxide are formed, the same amount is decomposed.

By increasing the oxygen concentration before the reaction, we shift the equilibrium to the right, towards the formation of carbon dioxide.

The use of a catalyst will in no way affect the shift in the chemical equilibrium of the system.
