Question

You are given a container in which H2 (g), N2 (g), and NH3 (g) are in equilibrium with each other at 120 C. Answer the following questions given that the formation of ammonia is exothermic.

Thank you for any help you can provide!

M T W R F You are given a container in which H Naou, and NH are in equilibrium with each other at 120°C. Answer the following questions given that the formation of ammonia is exothermic. 1. Write the balanced chemical equation which describes this equilibrium. 2. Explain what influence the removal of H2 from the container will have on the equilibrium (explain in terms of INH

Explanation / Answer

1) N2(g) + 3H2(g) <===> 2NH3(g)

2) If the H2 is removed from the contained then reaction will move backwards forming more H2 and thery by reducing amount of NH3 present in the container.

3) For the given reaction if we increase the volume the pressure will decrease. By le chatelier's principle if the pressure decreases then reaction proceeds such that to try to maintain the pressure. Here backward reaction produces more number of moles hence raction will move backwards and moles of NH3 will decrease.

4) As the reaction is exothermic reducing the Temperature will favor the forward reaction and hence reducing the T will result in the formation of more NH3.
