Indicate in which direction and why the equilibrium of the following system will shift: N2 + O2 = 2NO

Indicate in which direction and why the equilibrium of the following system will shift: N2 + O2 = 2NO with decreasing temperature, if the direct reaction is endothermic.

According to Le Chatelier’s rule, with a decrease in temperature, equilibrium shifts towards an exothermic reaction.
This reaction is endothermic towards the forward reaction and exothermic towards the reverse reaction.
This means that with a decrease in temperature, the equilibrium system of this reaction will shift towards the reverse reaction (towards the reagents).
