Which of the following statements are true about reaction mechanisms? I.A rate law can be written from the molecularity of the slowest elementary step.
II.The final rate law can include intermediates.
III.The rate of the reaction is dependent on the fastest step in the mechanism.
IV.A mechanism can never be proven to be the correct pathway for a reaction.

Question

I. True, because the rate law is determined by the slowest step, also known as the rate-determining step, which dictates the overall reaction rate. IV. True, because while mechanisms can be supported by experimental evidence, they cannot be definitively proven as the only pathway for a reaction; there may always be alternative pathways or mechanisms that have not been considered or discovered.
