Question

Destructive hydrogenation is best to occur at which temperature?

(a) Higher

(b) Moderate

(c) Lower

(d) None of the mentioned

The question was asked in an online quiz.

My question is taken from Kinetic and Thermodynamics of Hydrogenation Reaction in section Hydrogenation of Unit Processes

Answer 1

Right option is (a) Higher

The explanation is: Destructive hydrogenation or hydrogenolysis would be more apt to occur at higher temperatures, for all reaction velocities are increased, and the specificity of a catalyst is, in general, markedly reduced.
