← ScienceWhich process governs catalyst selectivity during parallel reactions?
A)Preferential transition state stabilization✓
B)Increased reactant adsorption kinetics
C)Enhanced product desorption constant
D)Reduced catalyst site blocking
💡 Explanation
The catalyst directs the reaction via preferential transition state stabilization of one pathway. Because the activation energy becomes lower for these pathways, product formation favors those, rather than other possible products where there's comparatively less catalytic impact.
