... The most negative can be is thus –1/2 mol. (Note, too, that nH2 = 11/2 mol and nN2 = 5/2 mol when = –1/2 mol.) If N2 and H2 react to form more NH3, then will be positive. The maximum will be determined by the limiting reagent: does one deplete H2 first, or N2? Since every mole of N2 that rea ...

Chemical equilibrium
In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations which have no further tendency to change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and backward reactions are generally not zero, but equal. Thus, there are no net changes in the concentrations of the reactant(s) and product(s). Such a state is known as dynamic equilibrium.
