← ScienceWhich outcome lowers a reaction vessel's overall temperature when using platinum catalysts?
A)Increased catalytic surface area coverage
B)Decreased activation energy requirement
C)Increased rate of product diffusion✓
D)Decreased adsorption enthalpy magnitude
💡 Explanation
Increased product diffusion carries energy from the Pt surface into bulk solution; because product molecules depart before transferring all energy as heat, therefore rate of catalytic product separation lowers vessel temp, rather than allowing total equilibration.
