This video covers how to deduce to the overall equation from the reaction mechanism and also how to deduce the rate expression from the elementary steps.
They are still there they don't cancel out, but they (K1, K-1 and K2) can be simplified in to a new constant (seems confusing cause he uses K2 again). That doesn't matter though as the orders of reaction matches the ones of the expermental one
@@MSJChem oh I get it, if the slow step is the first step, I can just look at that to get the rate. But if the slow step is the 2nd step, I can just look at the overral equation and get the rate.
Im confused, what is it that we would actually have to do in a question since the ib state that we dont have to propose a reaction mechanism in the current syllabus, could you please help? :)
First exams 2025: Evaluate proposed reaction mechanisms and recognise intermediates. Distinguish between intermediates and transition states, and recognise both in energy profiles of reactions. Include examples where the rate-determining step is not the first step. Proposed reaction mechanisms must be consistent with kinetic and stoichiometric data.
