For a reaction A → B, E a = 10 kJ mol –1 , Δ H = 5 kJ mol –1 . Thus, potential energy profile for this reaction is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
For reaction, A 
B.
E a = 10 kJ/mole , Δ H = 5 kJ/mole
Rxn endothermic because Δ H (+)
Δ H = E a – E b
5 = 10 – E b
E ab = 10 – 5 = 5 kJ/mole.
