    I have to work out the rate constant for a reaction, the sheet says: rate =k * [I-] *[S2O8] and the concentration for I- is the independent variable so which concentration of I- do I use in the equation (I have 5 different concentrations) ?

    Basically all the concentrations you have are for different "experiments" (to investigate the effect of different conc.s of different stuff blah blah).
    as long as you just stickk to one row, any row but as long as you stick to it and sub in your values youll find k.

    if you still struggle post the table if you can

    This is an "iodine clock experiment," what would you expect the value of k to be?

    i havent done this chapter in quite a while so i dont know off the top of my head.
    Best way to do it is just do (for only one row) rate/concentration of each thing that appears in the rate equation
