<span>The chemical reaction of a reversible reaction is actually
governed by Le Chatelier’s principle. It states that when more reactants are
introduced into the system, the reaction will proceed forward to create more
products. So since Hydrogen is a reactant and Nitrogen is also reactant so
adding more Hydrogen makes more products hence reducing the Nitrogen
concentration.</span>
