3H2(g)+N2(g)⇌2NH3(g);⋅∆H=+ve
As the formation of ammonia from its constituent elements is an exothermic reaction.
Thus, energy is released during the reaction.
So, on increasing the temperature, the reaction is favoured in backward direction. As per
Le-Chatelier's principle, change made in one direction/site is opposed by movement of reaction in opposite direction.
