Question

2CO(g) + O2(g) = 2CO2(g)

a. The amount of O2 is increased.
forward, reverse, or no change.

Answer 1

The system will shift to the right (Forward).

Step-by-step explanation:

Based on the equilibrium:

2CO(g) + O2(g) ⇄ 2CO2(g)

If the amount of O2 is increased: The equilibrium will shift to the right trying to decrease this concentration following the Le-Ch principle that says:

A change in an equilibrium will be counteracted by the system producing a response that restore the initial state.
