Which consequence prevails when catalytic hydrogenation proceeds too rapidly?

💡 Explanation

Rapid hydrogenation can lead to reduced stereoselectivity because mass transport limitations overtake the catalyst's inherent selectivity; therefore, products form closer to kinetic control rather than thermodynamic control, leading to a racemic mixture, rather than a single stereoisomer.
