Which 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.
