It is well known that the emission of greenhouse gases such as carbon dioxide presents a very grave threat to the environment. Attempts are ongoing to absorb (sequester) this gas by several means. One such approach involves the use of vegetation, as plants utilize the gas by means of photosynthesis. One such plant, which has shown great promise, is the "Spekboom" (Portulacaria Afra) which is endemic to the semi-arid Karoo region of the Eastern Cape. • It has been estimated that fully-grown Spekboom can absorb 3.8 tonnes of carbon per hectare of plants per year. If the system is fully functional, South Africa can generate 234.5 x 10° kWh of electricity 1.1 per year. Assume that 1559 pounds of CO2 is emitted per year per Megawatt-hour (MWh) of electricity generated in the country. Determine, by means of the use of conversion factors, how many square kilometres of Spekboom could theoretically absorb all of this carbon dioxide?

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?
