use the graph to calculate the number of moles of gas that are released at 20s and 105s. Workout the difference then divide by 85s, this will give you the average rate

look here it shows you how to do it

i get this like really long figure like i looks really wrong to me (2.823529412 x 10-5)

basically i found the difference which was 2.4 x 10^-3 mols and then divided by 85s

thats what I got to, its correct I think, the number of moles that is reacting on your graph is small, so the rate is going to be very small too.
