**DO NOT need all of them done if do not want too, BUT it
would be awesome if a few from both sides were done with work
shown. I have no idea how to do it. Thank you so much.
In order to Calculate the rate for both reactions (trial one
and try to) use the change in concentration and change in time
information between three and four minutes.
