The equilibrium constant expression for the reaction N₂ (g)+ 3H₂ (g)⇔ 2NH₃ (g)is ________.

Question

Quizplus · Accepted Answer

The equilibrium constant expression includes the concentrations of the reactants and products raised to their coefficients in the balanced chemical equation, with products divided by reactants. The correct expression is determined by writing the concentrations of the compounds in the numerator and denominator of the equation in the correct order. In this case, the correct expression is Option B, because it has the concentrations of the products (NH₃) in the numerator and those of the reactants ([N₂] and [H₂]) in the denominator, all raised to their coefficients in the balanced equation (2 and 3).
