Is the law of mass action rigorously true for equilibria problems or is it a magic show?
It makes the assumption that the rate of a reaction in a given direction is governed by a one step process.
This does not square with what I understand, that the rate is governed by the slowest step in a reaction
My question is, for problems involving equilibria in the real world is the law of mass action used as is, or is a modified version with experimentally determined coefficients used? If used as is, what is the justification?
