Answer #1

E2 : This is single step reaction mechanism.

In this step formation of double bond is in the limiting step. According to Hammonds postulates, transition state of the reaction resembles to reactant or product. It depends on the position of it.

When transition state is very far from product that means it is exothermic reaction and it is stable reaction.

Exothermic reaction evolves heat and so it is thermodynamically stable

Transition state in E2 mechanism is formation of double bond so the answer for this question is E2
