What is the equilibrium expression for the following reaction: N2 (g) 3 H2 (g) rightwards harpoon over leftwards harpoon with blank on top 2 NH3 (g)

Explanation:

For the reaction at equilibrium:

N₂ (g) + 3 H₂(g) ⇄ 2 NH₃ (g)

Since this is an equilibrium in the gas phase, the equilibrium expression is obtained from the partial pressures (P) of the products (NH₃) and reactants (N₂ and H₂) raisen to their stoichiometric coefficients:

the answer is definitely c.
