Step 1
First, we need to find the enthalpy of vaporization (ΔHvap) for hydrogen peroxide (H2O2). Unfortunately, the ALEKS Data tab is not available here, so we will use a standard value for ΔHvap of H2O2, which is approximately 55.3 kJ/mol. Show more…

The temperature at which the following process reaches equilibrium at 1.0 atm is the normal boiling point of hydrogen peroxide H2O2 (l) -> H2O2 (g). Use the following thermodynamic information at 298 K to approximate this temperature: Substance: H2O2 (l) H2O2 (g) ΔH° (kJ/mol): -187.7 -136.3 ΔG° (kJ/mol): -120.4 -105.6 S° (J/(K·mol)): 109.6 232.7

The temperature at which the following process reaches equilibrium at 1.0 atm is the normal boiling point of hydrogen peroxide. (R = 8.314 J/K • mol) H2O2(l) H2O2(g) Use the following thermodynamic information at 298 K to estimate this temperature. Substance: H2O2(l) H2O2(g) ΔH°f (kJ/mol): –187.7 –136.3 ΔG°f (kJ/mol): –120.4 –105.6 S° (J/K • mol): 109.6 232.7
