A balanced equation for the photochemical decomposition of Freon-11 is

  1. (A)\text{CCl}_3\text{F}(\text{g}) \xrightarrow{h\nu} 2\text{Cl}^\bullet(\text{g}) + \text{CClF}^\bullet
  2. (B)\text{CCl}_3\text{F}(\text{g}) \xrightarrow{h\nu} \text{CCl}_3^\bullet(\text{g}) + \text{F}^\bullet(\text{g})
  3. (C)\text{CCl}_3\text{F}(\text{g}) \xrightarrow{h\nu} \text{Cl}^\bullet(\text{g}) + \text{CCl}_2\text{F}^\bullet(\text{g})
  4. (D)\text{CCl}_3\text{F}(\text{g}) \xrightarrow{h\nu} 3\text{Cl}^\bullet(\text{g}) + \text{CF}^\bullet(\text{g})
