In a standard (Elimination Bimolecular) reaction pathway, what is the experimentally measurable over — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

An $E2$ reaction is defined mechanistically as a single-step, concerted process. The transition state requires the simultaneous physical collision and orbital overlap of exactly two separate species: the reacting base and the organic substrate. Consequently, the rate equation is $\text{Rate} = k[\text{Substrate}][\text{Base}]$, meaning it strictly follows second-order kinetics with an overall order of 2.
