← ScienceWhich outcome reduces the required energy input during cracking?
A)Increased catalyst surface area availability✓
B)Decreased average product molecular weight
C)Elevated reactor operating system pressure
D)Reduced gaseous phase reaction residence
💡 Explanation
Increased catalyst surface area lowers the activation energy because heterogeneous interfaces undergo adsorption, accelerating bond breakage via a catalytic mechanism, therefore more cracking occurs at lower temperatures rather than without catalysts at high energy demands.
