    I need to determine the Ka of some phenylboric acids, i have the the temperature σ, K and p, and think i need the hammet equation rearranged but not sure how to apply it. Any help would be good cheers

    Hammett: log (K/K0) = σp

    rearrange simple logarithms (in elementary mathematics for chemistry/any sciences in general - you gotta be able to do this though).

    K/K0 = exp (σp)

    I think your Ka in this case would be the K0.
    Make that the subject of your formula.
