All lessons of this unit:    • JEE 2027 Chemistry | Unit 8 Chemical Kinetics   How to get the rate law from a reaction mechanism for JEE Main and Advanced: order equals molecularity for an elementary step, the slow step as the rate-determining step, the fast pre-equilibrium method (k_obs = k2 K, Ea,obs = Ea2 + delta H1), the steady-state approximation, intermediates versus catalysts, peaks and valleys on an energy profile, and two solved problems, including ozone's negative order. Chapters 0:00 Introduction 0:31 Elementary steps: order equals molecularity 1:31 Slow step first: the rate-determining step 2:30 Fast pre-equilibrium, then the slow step 3:53 Steady state: the intermediate stays nearly constant 4:35 Energy profiles, and the big trap 5:26 Example 1: rate law of 2NO2 + F2, F atom as intermediate 6:38 Example 2: ozone pre-equilibrium, order minus 1 in O2 7:58 Quick revision: slow step, pre-equilibrium, energy profile A free JEE paper every day and a full JEE Main mock every Sunday: https://rankdeterminant.com/go/yt-dai...
