Consider the reaction mechanism. Which species would be a catalyst?

Step   Reaction                 

1           Cl 2 + Pt → 2 Cl + Pt

2           Cl + CO + Pt  → ClCO + Pt

3           Cl + ClCO  → Cl2CO 

overall  Cl2 + CO → Cl2CO

1. There are no catalysts in this mechanism

2. Cl

3. Cl2

4. CO

5. ClCO

6. Pt
