Question

The boiling point of methanol is 64.7 C. Calculate the equilibrium vapor pressure of methanol at 81 C. The enthalpy of vaporization of methanol is 37 kJ/mol.

Calculate the equilibrium vapor pressure of bromine above the pure liquid at 25 C. Use the thermochemical data available from the NIST Chemistry WebBook.

At 25 C, the partial pressure of CO2(g) in a bottle of soda water is 2 bar. Calculate the equilibrium concentration of dissolved carbon dioxide under these conditions. The standard Gibbs free energy of formation of CO2(aq) is -386. kJ/mol and ΔfG0[CO2(g)] = -394.4. kJ/mol.
