Calculating Ka

  1. May 6, 2007 #1
    Using [tex]\Delta \textrm{E}^{\circ}[/tex] values and the fact that [tex]\textrm{K}_{\textrm{w}}=10^{-14}[/tex], how would I find the [tex]\textrm{K}_{\textrm{a}}[/tex] value for the following reaction?:

    dEº = -RTlnK

    Dunno if that helps :/.

    Noobler sounds right.
    Rearrange to give:
    [tex]\frac{\Delta E}{-RT}=ln K_{a}[/tex]
    and solve for [tex]K_{a][/tex]
