### finding k

When looking at multiple mechanisms and asked to find the rate law and k that matches the desired overall reaction, how do you figure out if the rate law of the proposed mechanism is the same as the actual rate law?

I think you have to be given the actual rate law, or see which one makes the most sense based on the pre-equilibrium approach. I'm not sure this answers your question, if you have an example that may be more helpful.

I think you would need experimental data to determine this.

You'll likely need to be given the rate law or experimental data
