# What is the stoichiometric equation corresponding to the equilibrium mass action expression given below?

Without the equation this question cannot be answered, but I've added a link to a video which discusses the law of mass action. The video discusses the synthesis of ammonia reaction.

$3 {H}_{2} \left(g\right) + {N}_{2} \left(g\right) \to 2 N {H}_{3} \left(g\right)$

There are several other examples discussed as well.
