← ScienceWhich mechanism limits reaction velocity using surface catalytic converters?
A)Substrate adsorption follows Langmuir isotherm✓
B)Product desorption limits surface area
C)Catalyst poisoning decreases active sites
D)Temperature equilibrium inhibits gaseous diffusion
💡 Explanation
Substrate adsorption obeying the Langmuir isotherm limits reaction rates on catalytic converters because a monolayer forms, limiting reactant contact; therefore, the reaction stalls rather than accelerating indefinitely, unlike if unlimited multi-layer adsorption sites existed.
