In the reaction of nitrogen gas with oxygen gas to produce nitrogen oxide, what is the effect of adding more oxygen gas to the initial reaction mixture? the reaction is shown below. n2(g) + o2(g) ⇌ 2no(g)

The Equilibrium would shift to produce more NO

Explanation:

The reaction is;

N₂(g) + O₂(g) ⇆ 2NO(g)

When a reaction is at equilibrium then the forward reaction rate will be equivalent to the reverse reaction rate. Additionally, the concentration of the reactants and products are the same. From Le Chatelier's principle, additional reactants favor the formation of more products while additional products favor the formation of more reactants.For example, when more oxygen is added then more Nitrogen (II) oxide will be formed. Oxygen is a reactant and when increased it favors forward reaction which leads to the formation of more NO which is the product.
