What does the rate of the E2 reactions depend on?

Answer 1

Similar to SN2 reactions, the rate of E2 reactions is dependent upon the supplied nucleophile or base; an increase in one of these factors will result in an increase in the reaction's overall rate.

The rate of E2 (Elimination, bimolecular) reactions depends on the concentration of both the base and the substrate. It is also influenced by the structure and stability of the leaving group and the substrate. Additionally, the steric hindrance around the β-carbon affects the rate of the reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
