    I'm stuck on the analysis of results.
    1. Since it's a rate against time graph, would I work out the order using the gradient? The gradients I worked out weren't consistent.
    3. E.g. if at 44s the rate is 4.55 x 10^-5 and the concentration of I- is 0.4 mol dm-3, how would I work out the concentration of S208^2-
    I got the concentration as 1 mol dm-3. Is this right?
