For a reaction A rarr B, E_(a) = 10 kJ mol^(-1), DeltaH = 5 kJ mol^(-1) . Thus, potential energy profile for this reaction is:

{:(I.,E_(a)=15m "kJ mol"^(-1),,DeltaH=-70 "kJ mol"^(-1)),(II.,E_(a)=30"kJ mol"^(-1),,DeltaH=-15 "kJ mol"^(-1)),(II.,E_(a)=60 "kJ mol"^(-1),,DeltaH=+250"kJ mol"^(-1)):} If above reactions are at same frequency factor then fastest and slowest reaction are:
