Which outcome results when a platinum catalyst complex degrades in a packed bed reactor?

💡 Explanation

The activity is reduced; catalyst degradation lowers active surface area, impacting the reaction rate via decreased activity. The *Arrhenius equation* dependence of rate constant on temperature dictates that conversion diminishes, because the degradation reduces the pre-exponential factor rather than selectivity at a given temp.
