Which mechanism limits overall catalyst effectiveness due to temperature?

💡 Explanation

Catalyst active sites can undergo thermal deformation which destroys its specifically shaped surface meant for interaction in reactants at elevated temperatures. This reduces reaction due to the loss of active site; therefore deformation limits process performance rather than higher energy facilitating reaction.
