Ammonia is made from nitrogen and hydrogen. the energy change in the reaction is -92 KJ/mol.
the reaction is reversible and reaches equilibrium, answer the following
a- write the equation for the reaction
b- is the forward reaction endothermic or exothermic, explain your answer.
c- Explain why the yield of ammonia :
i- rise if you increase the pressure.
ii- falls if you increase the temperature.
d- What effect does increasing:
i- the pressure.
ii- the temperature.
have on the rate at which ammonia is made.
e- Why is the reaction carried out at 450 c rather than a lower temperature?
plz plz answer the questions, its so important
