Elementary Reactions Differential Rate Law

Postby Michelle Dong 1F » Mon Mar 05, 2018 5:21 pm

Just to clarify, we can't find the differential rate law for a complete reaction, just an elementary reaction? Why is that?

Differential rate laws can only be committed from experimental data like a linear graph or table of reactions but mechanisms can be computed from their elementary equations.

We can't find the rate law for a complete reaction because we don't know the whole process the reaction took to reach the final products. Unlike for thermodynamics, kinetics is not a state property, so the path it takes counts. Therefore it must be broken up into elementary steps.
