At 298 K, the dissolution of solid AB is characterized by ΔH∘=+12 kJ⋅mol−1\Delta H^\circ = +12\,\text{kJ}\cdot\text{mol}^{-1} and ΔS∘=+115 J⋅mol−1⋅K−1\Delta S^\circ = +115\,\text{J}\cdot\text{mol}^{-1}\cdot\text{K}^{-1}. Describe, with reasoning based on the signs and relative magnitudes of the thermodynamic quantities, whether this dissolution is thermodynamically favorable at 298 K.
