Nitrous oxide (N2O) decomposes at 600°C according to the balanced equation
2N2O(g) → 2N2(g) + O2(g)
A reaction mechanism involving three steps is shown below. Identify all of the catalysts in the following mechanism.
Cl2(g) → 2Cl(g)N2O(g) + Cl(g) → N2(g) + ClO(g) (occurs twice)ClO(g) + ClO(g) → Cl2(g) + O2(g)
