Answer 1

For the conversion of oxygen to ozone in the atmosphere, nitric oxide in gaseous phase acts as homogeneous catalyst.

Explanation:

Nitric oxide in the gaseous phase works as a homogenous catalyst for the conversion of oxygen to ozone in the environment. This is due to the fact that both the reactant and the catalyst are in the same phase (gas).
