← ScienceWhich outcome occurs when platinum catalysts promote hydrogen dissociation?
A)Increased reaction rates via surface adsorption✓
B)Decreased activation energy inhibits bonding
C)Poisoning of catalyst reduces reaction rates
D)Destabilization via induced dipole interactions
💡 Explanation
Hydrogen molecules dissociate into atoms via chemisorption, increasing reaction rates because the catalytic activity provides lower energy pathways forming adsorbed radicals, therefore accelerating reactions, rather than inhibiting because poisoning inhibits sites.
