Can some body plz help me on my homework. The problem is in the link image below (click to go to it)

http://img501.imageshack.us/img501/1126/helplr7.jpg" [Broken]

I'd know how to do that problem if it said "initial rate (M/s)" in the last column, but it says "Reaction time (seconds)" and I don't know what to do in that situation.

My guess is that I would need to somehow use that "Reaction time in seconds" to convert it into the initial rate, but I have noo idea how to. If I can do that I know the problem is easy, but I don't know how to. Please help!

Someone please correct me if I am wrong on this. I remember these as in you have to calculate the rate of change for X. When you calculate it the other concentrations can show no chage. Example:


----A---B---Rate M/s
1--1.0--2.0-----x
2--2.0--2.0-----x
3--1.0--1.0-----x

To calculate the rate for A you would use trials 1 and two because B is the same in this

Note: None of the values are negative, I just had problems if the hyphens were not in place, the table got messed up.
