That is the lab I have been working on. I've done the lab but I am answering the questions. I don't understand the Analysis question #1. How do I calculate the reaction rate for oxygen if I don't have its concentration?

2. Relevant equations

c = n/v

m = m/mr

r = k[h202]^m[NaI]^n

3. The attempt at a solution

Well I know it's completely wrong but I took the volumes recorded of the oxygen produced, converted to moles, divided by the volume of NaI + h202 which was 20ml and divided by 10 seconds (for each trial).
