Multiple Choice

For the phase transition,H2O2(  For the phase transition,H<sub>2</sub>O<sub>2</sub>(   )  \leftrightarrows H<sub>2</sub>O<sub>2</sub>(g) at 298 K, \Delta G<sup> \circ </sup>= 14.8 kJ/mol.Calculate  \Delta G when the partial pressure of hydrogen peroxide in a closed container is 1.00 torr.Will liquid H<sub>2</sub>O<sub>2</sub> spontaneously evaporate or will vapor phase H<sub>2</sub>O<sub>2</sub> spontaneously condense? A)   \Delta G = -16.4 kJ/mol; liquid H<sub>2</sub>O<sub>2</sub> will evaporate.  B)   \Delta G = -1.6 kJ/mol; liquid H<sub>2</sub>O<sub>2</sub> will evaporate.  C)   \Delta G = +14.8 kJ/mol; vapor phase H<sub>2</sub>O<sub>2</sub> will condense.  D)   \Delta G = +8.17 kJ/mol; vapor phase H<sub>2</sub>O<sub>2</sub> will condense.  E)   \Delta G = 0 kJ/mol; the system is at equilibrium.  ) \leftrightarrows H2O2(g) at 298 K, Δ\Delta G \circ = 14.8 kJ/mol.Calculate Δ\Delta G when the partial pressure of hydrogen peroxide in a closed container is 1.00 torr.Will liquid H2O2 spontaneously evaporate or will vapor phase H2O2 spontaneously condense?
