for the reaction at 298k 2NO2(g) ---> N2O4(g) the values of delta H and delta S are -58.03kJ and -176.6 J/K respectively. what is the value of delta G 298K?

assuming that delta H and delta S do not depend on temperature. what is the minimum temperature for this reaction to be spontaneous and is the reaction spontaneous or below the minimum temperature of spontaneity.
