Question

Submit Vinyl chloride (H2C= CHCl (Figure 1) ), the starting material used in the industrial preparation of poly (vinyl chloride), is prepared by a two-step process that begins with the reaction of Cl2 with ethylene to yield 1,2 dichloroethane as follows My Answers Give Up Correct If 10 and So had opposite signs for this reaction, no equilibrium temperature would exist because the reaction would be either always spontaneous or always nonspontaneous C12 (g) H2C-CH2 (g) ClCH2 CH2 Cl(1) = -217.5 kJ ASID = -233.9 J/K Part D You may want to reference ( pages 340-343) Section 9.13 while completing this problem. Since this reaction has an equilibrium temperature where the reaction goes from nonspontaneous to spontaneous, calculate the equilibrium temperature Express the temperature in kelvins to four significant digits Figure 1 of 1 eq Submit My Answers Give Up Vinyl chloride Incorrect Iry Again Provide Feedback Continue

Explanation / Answer

D)
At equilibrium temperature, Go = 0
Go = 0.0 KJ
Ho = -217.5 KJ
So = -233.9 J/K
= -0.2339 KJ/K

use:
Go = Ho - T*So
0.0 = -217.5 - T *-0.2339
T = 929.9 K
Answer: 929.9 K
