Chapter 17, Problem 17.98SP

Use the values of $\Delta$ G°, in Appendix B to calculate the standard free-energy change for the synthesis of dichloroethane from ethylene and chlorine.

${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}\text{(g})+{\text{ Cl}}_2\left(\text{g}\right)\stackrel{}{\to }{\text{CH}}_{\text{2}}{\text{ClCH}}_{\text{2}}\text{Cl}(l)$

Is It possible to synthesize dichloroethane from gaseous ${\text{C}}_{\text{2}}{\text{H}}_{\text{4}}$ and $C{l}_2$ at 25°C and 1 atmpressure?
