What would happend if NO were added to n2(g) o2(g) 2no(g) at equilibrium?

Answer 1

If NO is added to the equilibrium mixture of N₂(g), O₂(g), and 2NO(g), the system will respond according to Le Chatelier's principle. The equilibrium will shift to the left, favoring the formation of reactants (N₂ and O₂) to counteract the increase in NO concentration. This shift will result in a decrease in the concentration of NO and an increase in the concentrations of N₂ and O₂ until a new equilibrium is established.
