Which outcome occurs when a platinum catalyst degrades during ammonia oxidation?

💡 Explanation

Decreased platinum surface area lowers available active sites, limiting surface adsorption. The adsorption lowers reactants effective concentration. Therefore, nitrogen oxides production decreases because effective activation energy increases rather than equilibrium being affected, or conversion magically improving.
