These questions require more thought and integrate several concepts.
It would be very useful if we could use the inexpensive carbon in coal to make more complex organic molecules such as gaseous or liquid fuels. The formation of methane from coal and water is reactant-favored and thus cannot occur unless there is some energy transfer from outside. This problem examines the feasibility of other reactions using coal and water.
(a) Write three balanced equations for the reactions of coal (carbon) and steam to make ethane gas, C2H6(g), propane gas, C3H8(g), and liquid methanol, CH3OH(l), with carbon dioxide as a by-product.
(b) Using the data in Appendix J, calculate ΔH°, ΔS°, and ΔG° for each reaction, and then comment on whether any of them would be a feasible way to make the stated products.
