For the reaction N₂ + 3H₂ ⇌ 2NH₃, what is the equilibrium constant expression?
A.K = [NH₃]² / ([N₂][H₂]³)
B.K = [NH₃] / ([N₂][H₂])
C.K = ([N₂][H₂]³) / [NH₃]²
D.K = [NH₃]² / [N₂][H₂]
Explanation
Core Concept
Products over reactants, each raised to its coefficient: NH₃ squared, H₂ cubed. Coefficients become exponents in K.
Correct Answer
AK = [NH₃]² / ([N₂][H₂]³)
