    So I've finished my practical and have worked out the rate equation for the bromine clock reaction. However, my reaction is first order to all reactants not first order with respect to bromate and bromide ions and second order with respect to hydrogen ions. I have acknowledged this and discussed the possible reasons in my analysis, however what i want to know is, when calculating my rate constant do i use the correct equation or the one my results show?

    Thanks in advance.

    Why not do both?

    Having done this course last year id agree with Pigster and do both. You will get different values / rates which you can then link to your experimental methods and conditions etc. Nothing ever turns out as it should!
    If you can explain why they are different (conditions, measurements etc), all it can do is get you marks.
