Step 1
First, we need to find the Gibbs free energy change (ΔG) at 298.0 K using the given equilibrium constant (Kp) at 298.0 K. ΔG = -RT ln(Kp) where R is the gas constant (8.314 J/mol K), T is the temperature in Kelvin (298.0 K), and Kp is the equilibrium constant Show more…

The formation of methanol is important to the processing of new fuels. At 298.0 K, Kp = 2.25 x 10^4 for the reaction CO(g) + 2 H2(g) = CH3OH(l). If AH = -128 kJ/mol CH3OH, calculate Kp at 6°C.

The combustion reaction of liquid methanol CH3OH takes place according to the reaction: 2CH3OH (l) + 3O2 (g) -> 2CO2 (g) + 4H2O (l) (ΔHrxn = -1452.8 kJ/mol). Given the standard formation enthalpies of CO2 and H2O, the standard enthalpy of formation of CH3OH is: ΔHf (CH3OH) = +228.7 kJ/mol ΔHf (CO2) = -393.5 kJ/mol ΔHf (H2O) = -285.8 kJ/mol
