← ScienceWhich outcome is expected for a catalyst poison that selectively blocks active sites preventing pi-bond interactions?
A)Reduced catalytic reaction specificity✓
B)Increased catalyst surface area
C)Enhanced product inhibition kinetics
D)Accelerated catalyst thermal sintering
💡 Explanation
Reduced catalytic reaction specificity occurs because blocking pi-bond interactions via *steric hindrance* changes reactant adsorption. Therefore catalyst selectivity decreases, rather than increasing the surface area; product inhibition or thermal sintering are not the initial results.
