Does the activation energy necessary for creation of transition state in simple substitution reaction (let's say Sn2), correspond to energy difference between carbon-halogen bonding-antibonding molecular orbital?
And if so, why does transition state need to exist between carbocation intermediate and final product in Sn1?

I dont know the first answer without doing more research/looking at notes, but the second is because the carbocation is stable enough on it's own. a transition state is not stable at all, and is only seen extremely briefly, while the carbocation is stable (relative). But because it's a carbocation, it's extremely reactive and will immediately react.
for the first question, i would guess yes.

Well, thanks for trying anyway
