Answer
It includes one transition state
Explanation
Carbocation intermediate is involved in SN1 mechanism , so statement 1 is incorrect
No intermediate is involved in SN2 mechanism , so statement 2 is incorrect
SN2 mechanism take place in single step , so statement 3 is correct
Reaction mechanism determine the kinetics of the reaction but not determine the thermodynamic quantities like enthalphy, entrophy , free energy change of reaction because these quantities are state functions not path functions. So, statement 4 and 5 are incorrect.
