Answer:
decrease
Explanation:
because the equilibrium will shift to right side
As the concentration of N2(g) increases, the concentration of O2(g) will decrease because the equilibrium will shift to right side of the equation.
What is equilibrium of reaction?
The equilibrium of a reaction is a chemical reaction between the reactants that stays in a stable state before and after the completion of the reaction.
The given chemical reaction:
N2(g) + O2(g) ↔2NO(g)
From the reaction above, as the concentration of N2(g) increases, the concentration of O2(g) will decrease because the equilibrium will shift to right side of the equation.
