    1. The problem statement, all variables and given/known data

    Which side does the equilibrium favour?

    2. Relevant equations
    Equilibrium favours weak acid or weak base (I don't know why :frown:)

    3. The attempt at a solution
    Using the given pka values, since the reactant is the weaker acid, reactants are favoured. (Backward reaction is favoured).
    But why does equilibrium favour weak acid or weak base?

    Try to express the K of the reaction using Ka values for both acids.

    ##k=10^{-0.6}##

    That's your answer, isn't it?
