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!
