← ScienceWhich outcome occurs when a molecular sieve adsorbs larger-diameter molecules?
A)Reduced separation efficiency occurs✓
B)Enhanced catalytic activity arises
C)Increased structural framework stability
D)Greater thermal conductivity becomes induced
💡 Explanation
Reduced separation occurs because steric hindrance prevents entry into the pores, causing reduced separation efficiency due to decreased selective adsorption *diffusion*. Therefore, larger molecules disrupt intended *molecular sieving*, rather than enhance catalysis or inducing structural stability under normal conditions.
