← ScienceWhich outcome occurs from increased temperature during catalyst poisoning?
A)Increased side-product formation rate✓
B)Selective adsorption site availability increases
C)Effective catalyst surface area recovers
D)Poison dissociation rate declines
💡 Explanation
Increasing temperature provides the activation energy for reactions involving poisons through the Arrhenius equation; rather than reversing the *poisoning mechanism*, the accelerated poisoning leads to *increased side-product formation*, because adsorption sites become blocked, therefore impacting selectivity.
