Consider the following reaction: 2A(g)+B(g)→2D(g)\mathrm{2A(g)+B(g)\to2D(g)} ΔU∘=−10 kJ mol−1\Delta U^\circ=-10\ \text{kJ mol}^{-1} and ΔS∘=−44 J K−1\Delta S^\circ=-44\ \text{J K}^{-1} at 298 K. Identify the correct option with ΔG∘\Delta G^\circ for the reaction and spontaneity of the reaction at 298 K. (Given: R=8.31 J mol−1K−1R=8.31\ \text{J mol}^{-1}\text{K}^{-1})
