Which outcome results when a packed bed reactor's space velocity significantly increases during an exothermic catalytic reaction?

💡 Explanation

When the space velocity increases, the residence time of the reactants in the packed bed reactor decreases because reactants spend less time in contact with the catalyst, directly limiting the extent of the reaction. Therefore, lower conversion results, rather than hotspot formation, poisoning, or selectivity improvement, as these require different kinetic limitations.
