###### Problem Details

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-1•mol-1)

H2O2(l) ⇌ H2O2(g)

Use the following thermodynamic information at 298 K to determine this temperature.

Substance:                H 2O2(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

A) 120°C

B) 144°C

C) 196°C

D) 418°C

E) 585°C
