Which process limits the hydrogenation rate using transition metal catalysts?

A)Surface reaction-controlled Langmuir-Hinshelwood mechanism
B)Mass transport into the catalyst particle
C)Heat dissipation during hydrogen adsorption
D)Catalyst poisoning blocking surface sites

💡 Explanation

The Surface reaction-controlled Langmuir-Hinshelwood mechanism limits the reaction rate because adsorption and reaction steps determine overall speed; therefore, improving these steps accelerates hydrogenation, rather than limitations in mass transport or heat dissipation.
