Problem

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. (c) Calculate the equilibrium constant for the reaction.
 

Solution

We’re being asked to calculate the equilibrium constant (K) for the reaction of chloroethane with water at 25 ˚C.


Recall that ΔG˚ and K are related to each other:


ΔG°=-RT lnK
