The pre-equilibrium approximation is used to find the rate law for a reaction with a fast and reversible initial step. In this method, we first write the rate law based on the slow (rate-determining) step. Then, to eliminate any intermediates from the rate law, we use the fast initial step to solve for the intermediate concentration(s) in terms of reactant and/or product concentrations.

Thank you, this was better explained here than in my kinetics section of physical chemistry course in college, lol.

[@MrPotatoPro]

This was very well explained. Thankyou.
