In the reaction represented by the equation n2(g) + 3h2(g) 2nh3(g), the
forward reaction is exothermic. which set of conditions would give the best yield of
ammonia at equilibrium?
a) 800 atmospheres and 2000 oc
b) 1 atmosphere and 500 o
c
c) 1 atmosphere and 2000 o
c
d) 800 atmospheres and 500 o
c

The chemical equilibrium is:



The best conditions, taking into account Le Chatelier's Principle, will be low temperature and high pressure, because is an exothermic reaction and there are more moles of gases in the reactants than in the products.
