← ScienceWhich outcome occurs when platinum catalyst surface hydrogen coverage drops during hydrogenation?
A)Reaction slows, increased alkane byproduct✓
B)Ester hydrolysis, forming alcohol, acid.
C)Catalyst poisoning forming platinum oxide
D)Increased amine conversion rate overall
💡 Explanation
The reaction rate will drop and byproduct formation will rise because the Langmuir-Hinshelwood mechanism requires adsorbed hydrogen; therefore, alkane formation increases rather than amine conversion or ester hydrolysis given platinum limitations.
