question 113

Multiple Choice

For the phase transition,H₂O₂( ) $\leftrightarrows$ H₂O₂(g) at 298 K, $\Delta$ G ^$\circ$ = 14.8 kJ/mol.Calculate $\Delta$ 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?

• 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."
