How many molecules of ammonia are formed in the equation: #N_2 + 3H_2 → 2NH_3#?
Well clearly stoichiometry dictates that 2 equiv of ammonia are formed in the stoichiometric reaction. But there is a catch......
The formation of ammonia is probably one of the best studied equilibrium reactions. This is an equilibrium reaction that requires high pressures, and high temperatures to provide acceptable rates. The one thing this reaction has got going for it is that the ammonia product is condensable (perhaps on a cold finger), whereas the reactants are essentially non-condensable.
