For the Phase Transition H₂O₂ (L) ⇄ H₂O₂ (G) at 298

question 23

Multiple Choice

For the phase transition H₂O₂ (l) ⇄ H₂O₂ (g) at 298 K, $\Delta$ G $\degree$ = 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 ₂O₂ spontaneously evaporate, or will vapor phase H₂O₂ spontaneously condense?

• A)(\(\Delta\)G =16.4 kJ/mol; liquid H₂O₂ will evaporate.)
• B)(\(\Delta\)G =1.6 kJ/mol; liquid H₂O₂ will evaporate.)
• C)(\(\Delta\)G = 14.8 kJ/mol; vapor-phase H₂O₂ will condense.)
• D)(\(\Delta\)G = 8.17 kJ/mol; vapor-phase H₂O₂ will condense.)
• E)(\(\Delta\)G = 0 kJ/mol; the system is at equilibrium.)
