What is the equilibrium constant expression, $K_c$, for the reaction: $2SO_2(g) + O_2(g) \rightleftharpoons 2SO_3(g)$?

A

Kc = [SO₃] / ([SO₂][O₂])
B

Kc = [SO₃]² / ([SO₂]²[O₂])
C

Kc = ([SO₂]²[O₂]) / [SO₃]²
D

Kc = ([SO₂][O₂]) / [SO₃]

Hint Hint

Hint

Apply the general rule: products over reactants, each raised to their stoichiometric coefficients
