← ScienceWhich process governs reaction initiation rate in catalytic converters?
A)Surface adsorption and reactant interaction✓
B)Support material thermal expansion dynamics
C)Substrate gas diffusion equilibrium constant
D)Internal bypass valve conductance parameters
💡 Explanation
Surface adsorption dictates the catalytic reaction rate because reactants must first adhere to the converter's surface; therefore, adsorption efficiency controls the initiation, rather than material expansion, gas diffusion, or valve parameters that influence overall throughput.
