What would happen if no were added to n(g)+o2=2no(g) at equilibrium?

A. More N₂ and O₂ would formed.

Explanation:

Le Chatelier's principle states that "when any system at equilibrium for is subjected to change in concentration, temperature, volume, or pressure, then the system readjusts itself to counteract the effect of the applied change and a new equilibrium is established that is different from the old equilibrium".

N₂ + O₂ ↔ 2 NO

According to Le Chatelier's principle, the addition of NO will result in shifting the system to lift to increase N₂ and O₂ concentrations and reduce the stress of NO addition and readjust the equilibrium again. So, More N₂ and O₂ would formed.
