We’re being asked to calculate the free energy change (ΔG˚) for the reaction of chloroethane with water at 25 ˚C.
We can calculate for ΔG˚ using the following equation:
ΔH˚ = 26.6 kJ mol–1
ΔS˚ = 4.81 J K–1 mol–1
T = 25 ˚C + 273 = 298 K
The reaction of chloroethane with water in the gas phase to produce ethanol and hydrogen chloride has ΔH° = +26.6 kJ mol -1 and ΔS° = +4.81 J K-1 mol-1 at 25°C. (b) Calculate ΔG° for the reaction. What can you now say about whether the reaction will proceed to completion?
