Question

Hf S Gf H2(g) 0 kJ/mol 130.6 J/mol 0 kJ/mol N2(g) 0 kJ/mol 191.5 J/mol 0 kJ/mol NH3(g) -45.9 kJ/mol 193 J/mol -16 kJ/mol
3H2(g) + N2(g) --> 2NH3(g) Calculate the equilibrium constant at 25C and 500C assumingthat H and S are independent of one another. If thetemp is increased to 500C what direction will the reaction shift,if there is a shift. Will an increase in pressure affect theequilibrium of this reaction? THANK U LIFESAVER!

Explanation / Answer

     According Le Chatelier s principle ifthe pressere increases the equilibrium shifted to forward reaction.As the similar manner as we increase the temperature thenthe reaction shifted to backward direction.So what we understandfrom this at low temparetare & high pressere the reaction isfavourable for ammonia synthesis by Habbeir process.
