Correct Option - 1
Detailed Solution:When the reactants and the catalyst are in different phases, then the catalysis is known as heterogenous catalysis.
1. N? (g) + 3H? (g) - (Fe (s)-> 2NH? (g) (Heterogenous catalysis)
2. 2SO? (g) + O? (g) - (NO (g)-> 2SO? (g) (Homogenous catalysis)
3. C? H? O? (aq) + H? O (l) → C? H? O? (aq) + C? H? O? (aq) (Homogenous catalysis)
4. NO (g) + O? (g) → NO? (g) + O? (g)
