Select ALL examples of homogeneous catalysis.

ANO in the lead chamber process, with gaseous $SO X_{2}$ and $O X_{2}$
B $Fe X^{3 +}$ in the reaction of aqueous $I X^{-}$ with aqueous $S X_{2} O X_{8} X^{2 -}$
CFe in the Haber synthesis of $NH X_{3}$
DNi in the hydrogenation of an alkene

Answer: A, B

Homogeneous catalysis has the catalyst in the same phase as the reactants: gaseous NO with gaseous reactants, and aqueous

Fe X^{3 +}

in solution. Solid Ni or Fe with gaseous or liquid reactants is heterogeneous.
