Water/aqueous solution has H2O, H+, -OH. They are not intermediates as they are all the time present in water, and therefore can be present in rate laws if involved in the slow step of a reaction.

Some reactions are referred to as acid catalyzed and H+ is present in the rate law. Meaning the more acidic the solution the faster the reaction.

Please ask me about this in my additional review session this coming Friday March 3 at 4pm in CS50.

Yes this sounds like problem 15.101

Ohhh, so the review session will also go over post-midterm materials? That's also good to hear. I had a few questions regarding chemical kinetics after Quiz 2.

I think the review session today is limited to the midterm and questions within that. But Do you know if there will be any review of the new organic material?

If there is 2 transition states with 2 steps involved in a reaction, can there only be 1 intermediate or is it possible to have 2 intermediates?

there can be 2 transition states in an electorphillic reaction
