Question

Use LeChâtelier's principle explain why the concentration of NO at equilibrium increases when the reacuon takes place at higher temperatures

Answer 1

increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

Explanation:

The concentration of NO at equilibrium will increase when the reaction takes place at a higher temperature because increasing the temperature shifts the equilibrium in the direction of the reaction in which heat is absorbed.

The reaction is an endothermic reaction.

                            N₂  + O₂  + heat  ⇄  2NO

According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed the system will adjust itself in order to annul the effect of the change".

• In an endothermic reaction, heat is usually absorbed.
• We see that in the backward reaction, heat is absorbed.
• If the temperature of this reaction is increased, the backward reaction is favored more.
• Since the reactants are combining better, more products NO results.
