12.102 A chemical engineer is working to optimize the production of acrylonitrile to be used in the manufacture of carbon fibers. The reaction being used is the combination of propene gas, ammonia, and oxygen. The reaction is normally carried out at moderately high temperatures so all species are in the gas phase. (a) Write the equilibrium constant expression for this reaction. (b) The boiling point of acrylonitrile is 77 °C, and that of propene is -48 °C. What would the equilibrium expression be if this reaction were carried out at room temperature? (c) What characteristic of this reaction might cause the engineer to desire carrying out this reaction at room temperature?

Disulfides are compounds that have S— S bonds, like peroxideshave O— O bonds. Thiols are organic compoundsthat have the general formula R— SH, where R is a generichydrocarbon. The SH- ion is the sulfur counterpart ofhydroxide, OH-. Two thiols can react to make a disulfide,R— S— S— R. (a) What is the oxidation state of sulfur ina thiol? (b) What is the oxidation state of sulfur in a disulfide?(c) If you react two thiols to make a disulfide, are youoxidizing or reducing the thiols? (d) If you wanted to converta disulfide to two thiols, should you add a reducingagent or oxidizing agent to the solution? (e) Suggest whathappens to the H’s in the thiols when they form disulfides.
