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:

$\overline{){\mathbf{\Delta G}}{\mathbf{°}}{\mathbf{=}}{\mathbf{\Delta H}}{\mathbf{°}}{\mathbf{-}}{\mathbf{T\Delta S}}{\mathbf{°}}}$

We’re given:

ΔH˚ = 26.6 kJ mol–1

ΔS˚ = 4.81 J K–1 mol–1

T = 25 ˚C + 273 = 298 K
