Jones Company produces two products, A and C, at a cost of $150,000 in a joint process. The production process yields 20,000 pounds of product A and 15,000 pounds of product C. Both product A and C are saleable at the split-off point for $20 per pound and $15 per pound, respectively. Product A can be processed further at an additional cost of $160,000 to produce product B which would sell for $30 per pound. Product C can be processed...

The conversion of methane into products that contain two or more carbon atom, such as ethane, C2H2, is a very important industrial chemical process. In principle, methane can be converted directly into ethane and hydrogen. (1) 2CH4(g) C2H6(g) + H2(g) In practice, however, this reaction is carried out in the presence of oxygen: (2) 2CH4(g) + 1/2 O2(g) C2H6(g) + H2O(g) a) Using the thermodynamic data at 298K, determine ΔG° for each reaction. ΔGf° (kJ/mol) ΔGf° (kJ/mol) CH4(g) H2(g) 0...
