Which energy-profile feature distinguishes a catalyzed pathway from an uncatalyzed one?
A.A lower activation-energy peak
B.Products at lower energy
C.Reactants at higher energy
D.No transition state
Explanation
Core Concept
The catalyzed profile shows a smaller barrier (sometimes split into more steps), while reactants and products keep identical energies — ΔH unchanged.
Correct Answer
AA lower activation-energy peak
