N 2 (g) + 3 H 2 (g) --> 2 NH 3 (g)

Chemical Equilibrium. N 2 (g) + 3 H 2 (g) --> 2 NH 3 (g). A + B C + D. Many reactions do not go to completion - under the given conditions it is possible that not all of the reactants are consumed. Instead the extent of the reaction is determined by the equilibrium point .
