    Answer is: ΔG for methylamine is 18.85 kJ/mol.

    ΔG = R·T·lnK.

    ΔG is Gibbs energy.

    T is the temperature on the Kelvin scale.

    R is ideal gas constant.

    R = 8.314 J/mol ·K.

    T = 25°C = 293.15 K.

    Kb = 0.00044.

    ΔG = - 8.314 J/mol·K · 293.15 K · ln (0.00044).

    ΔG = 18836.85 J = 18.84 kJ.
