    d. ΔG°rxn is positive and the reaction is spontaneous in the reverse direction.

    Explanation:

    ∵ ΔG°rxn = - RTlnK.

    When lnK = negative, ΔG°rxn = - RT ( - Ve).

    ∴ ΔG°rxn is positive.

    When ΔG°rxn is:

    negative: the reaction is spontaneous in the forward direction.

    zero: the reaction is at equilibrium.

    positive: the reaction is non-spontaneous in the forward direction and spontaneous in the reverse direction.

    So, the right choice is:

    d. ΔG°rxn is positive and the reaction is spontaneous in the reverse direction.
