Chapter 6, Problem 42P

The reaction of chloroethane with water in the gas phase to produce ethanol and hydrogen chloride has $\Delta H°=+26.6kJmo{l}^{-1}$ and $\Delta S°=+4.81J{K}^{-1}mo{l}^{-1}$ at 25°C.

(a) Which of these terms, if either, favors the reaction going to completion?

(b) Calculate? G° for the reaction. What can you now say about whether the reaction will proceed to completion?

(c) Calculate the equilibrium constant for the reaction.

(d) In aqueous solution the equilibrium constant is very much larger than the one you just calculated. How can you account for this fact?
