In chemical kinetics , we learn that in a reversible reaction ,both the forward reaction and reverse reaction occur at the same time. At equilibrium , the rates are the same. For example:Production of ammonia NH3 .During the production of ammonia both the forward & reverse reaction is present .
3H2(g)+N2(g)⟶2NH3(g)3HX2(g)+NX2(g)⟶2NHX3(g) forward reaction
2NH3(g)⟶3H2(g)+N2(g)2NHX3(g)⟶3HX2(g)+NX2(g) reverse reaction
Now come to the Gibbs free energy.
Under standard condition(298K) , it can be calculated that the reaction is forwardly favored (forward reaction is spontaneous,and thus the decomposition of NH3 is non-spontaneous). I understand H2 and N2 will produce more NH3.My question is at this situation will NH3 decompose into H2 and N2 to some extent(though it is a non-spontaneous process)?.But chemical kinetics tells that both reaction(not necessarily same rate) have to be present to create equilibrium in future.
