The production of polyvinyl chloride, a common type of plastic, is produced by the reaction of chlorine gas and ethene, according to the reaction

Cl2 (g) + H2C=CH2 (g) → ClCH2CH2Cl(l)

and the enthalpy change for the reaction is -52 kcal/mol. Is this reaction spontaneous at all temperatures?

(hint: there is a table in chapter 7 that will help you answer questions about spontaneity and temperature dependance. Think about what you’re told in this problem. In addition, you do need to correctly make an inference to answer the question.)

A.Yes, it is spontaneous at all temperatures.

B. No, it is nonspontaneous at all temperatures.

C. It is spontaneous at high temperatures and non-spontaneous at low temperatures.

D. It is non-spontaneous at high temperatures and spontaneous at low temperatures.

E. It cannot be determined from the information provided.
