The Kc expression for a reaction is written as:

Kc = ( [H₂O]² [Cl₂]² ) / ( [HCl]⁴[O₂] )

Which reaction below best corresponds to this Kc expression? ( The = symbol is used to represent equilibrium arrows in the chemical equations.)

A) 2 H₂O _(l) + 2 Cl_{2 (g)} = 4 HCl _(aq) + O_{2 (g)}

B) 2 H₂O _(g) + 2 Cl_{2 (g)} = 4 HCl _(aq) + O_{2 (g)}

C) 4 HCl _(aq) + O_{2 (g)} = 2 H₂O _(g) + 2 Cl_{2 (g)}

D) 4 HCl _(aq) + O_{2 (g)} = 2 H₂O _(l) + 2 Cl_{2 (g)}
