Chapter 4, Problem 4.13E

Calculate $\Delta G°\left(25°\text{C}\right)$ for this chemical reaction, which is the hydrogenation of benzene to make cyclohexane:

${\text{C}}_{\text{6}}{\text{H}}_{\text{6}}\left(l\right)+{\text{3H}}_{\text{2}}\left(\text{g}\right)\to {\text{C}}_{\text{6}}{\text{H}}_{12}\left(l\right)$

Would you predict that this reaction is spontaneous at constant $T$ and $p$? Use data in Appendix 2.
