Chapter 6, Problem 6(choose chapter or problem)
The addition of water to ethylene to yield ethanol has the following thermodynamic parameters:
\(\mathrm{H}_{2} \mathrm{C}=\mathrm{CH}_{2}+\mathrm{H}_{2} \mathrm{O} \rightleftarrows \mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}\ \ \left\{\begin{array}{l} \Delta \mathrm{H}^{\circ}=-44 \mathrm{~kJ} / \mathrm{mol} \\ \Delta S^{\circ}=-0.12 \mathrm{~kJ} /(\mathrm{K} \cdot \mathrm{mol}) \\ K_{\mathrm{eq}}=24 \end{array}\right. \)
(a) Is the reaction exothermic or endothermic?
(b) Is the reaction favorable (spontaneous) or unfavorable (nonspontaneous) at room temperature (298 K)?
