The conversion of natural gas, which is mostly methane,into products that contain two or more carbon atoms, suchas ethane (C2H6), is a very important industrial chemicalprocess. In principle, methane can be converted into ethaneand hydrogen: 2 CH4(g)----->C2H6(g) + H2(g) In practice, this reaction is carried out in the presence ofoxygen: 2 CH4(g) + 12O2(g)---->C2H6(g) + H2O(g) (a) Calculate K for these reactionsat 25 °C and 500 °C. (b) Is the difference in ΔG° forthe two reactions due primarily to the enthalpy term (ΔH)or the entropy term 1-TΔS2? (c) Explain how the precedingreactions are an example of driving a nonspontaneousreaction, (d) The reaction of CH4 and O2 to form C2H6 and H2O must be carried out carefully to avoid a competingreaction. What is the most likely competing reaction?

Prof. Neiman and Prof. James were first to discovered in 1973 that chlorofluorocarbons (CFCs) were depleting the Earth’sozone layer when released into the atmosphere. Once they reach the stratosphere, Clis released from the CFCs molecules by interaction with UV light. Free Cl atoms areable to react with ozone in a catalytic cycle that converts O3into the more stable O2.It is estimated that a single Cl atom is able to react with∼100000 O3molecules.Although CFCs production was banned in 1996, there are still a substantial numberof motor vehicle air conditioners (MVACs) that use CFC-12 (CF2Cl2) as refrigerant.The average CFC-12 emission rate from operating MVACs has been estimated tobe 59.5 mg per hour per vehicle (Zhang et al.Environ. Sci. Technol. Lett.2017).How much chlorine, in kg, is added to the atmosphere in a year due to 100 millionMVACs using CFC-12 as refrigerant?

Suppose you are brewing beer, and you want to estimate how long it will take to complete the fermentation process. You place1.00 kgof sucrose(MM=342.3 g/mol)and yeast in your fermentation vessel and add water to a final volume of3.50 L. You decide that your reaction will be considered completed when the concentration of sugar decreases to0.0100M. How long will it take (in minutes) from the start of the reaction to the completion of the reaction?
