What wpuld happen if NO were added to N2(g) O2(g) 2NO(g) at equilibrium?

Answer 1

If NO were added to the equilibrium reaction N₂(g) + O₂(g) ⇌ 2NO(g), the system would respond by shifting to the left to counteract the change, according to Le Chatelier's principle. This shift would result in the conversion of some NO back into N₂ and O₂, thus partially restoring the equilibrium. Consequently, the concentrations of N₂ and O₂ would increase while the concentration of NO would decrease until a new equilibrium is established.
