How many of these reactions are homogeneously catalyzed?
(i) 2SO2(g)+O2(g)NO(g)−−−−→2SO3(g)
(ii) C12H22O11(aq.)+H2O(ℓ)H2SO4(ℓ)−−−−−−→C6H12O6Glucose(aq.)+C6H12O6Fructose(aq.)
(iii) 2SO3(g)+O2(g)Pt(s)−−−→2SO3(g)
(iv) N2(g)+3H2(g)Fe(s)−−−→2NH3(g)
(v) 4NH3(g)+5O2(g)Pt(s)−−−→4NO(g)+6H2O(g)
(vi) CH3COOCH3(ℓ)HCl(ℓ)−−−−→CH3COOH(aq.)
(vii) Vegetable oils (ℓ)+H2(g)Ni(s)−−−→ Vegetable ghee
All the reactants, products and catalysts need to be in the same phase. i, ii and vi are homogenously catalyzed.
