Which risk increases significantly when optimizing catalytic reactor geometry?

💡 Explanation

Inadequate active metal dispersion risk increases because smaller particles tend to aggregate during high-temperature processing due to Ostwald ripening. This aggregation decreases surface area and therefore reactant interaction, rather than the intrinsic orbital arrangement, influencing reaction selectivity.
