1 Methane is greenhouse gas that is about 23 times more effective on a molecular basis thancarbon dioxide in causing global warming. Methane is emitted by a variety of anthropogenicsources, including rice fields and cattle (IPCC,2001). According to a recent study Neue (1993),rice fields annually produce 20-100 teragrams (1Tg= 1 million metric tons) of methane throughanaerobic decomposition (methanogenesis) of organic materials that are either applied to ornative to the fields. Estimating annual methane emissions of approximately 500 Tg (Ciceroneand Oremland 1988) rice growing contributes 5% to 20% of annua anthropogenic methaneemissions. Using formic acid as an example of an organic that is anaerobically reduced.a) Calculate the molar ratio of methane production to carbon dioxide production whenformic acid (CHOOH) is reduced. Reaction products will include methane, carbon dioxideand water.b) Calculate the mass and volume of methane emitted from reducing 161 g of formic acid.Assume conditions of standard temperature and pressure (STP; T=25 C and P= 1 atm) andeventual emission of all products to the gas phase.
