Natural gas (mostly methane, CH4) is very abundant in many Middle Eastern oil fields. However, the costs of shipping the gas to markets in other parts of the world are high because it is necessary to liquefy the gas, which has a boiling point of â164 âC. One possible strategy is to oxidize the methane (in a 1:1 mole ratio) to methanol, CH3OH, which has a boiling point of 65 âC and can therefore be shipped more readily. Substance ÎHâf (kJ/mol) CH4(g) â74.8 CH3OH(l) â238.6 CO2(g) â393.5 H2O(l) â285.83 O2(g) 0 Part B Calculate the standard enthalpy changes for the combustion of a mole of methane and the combustion of a mole of methanol. Enter the enthalpy for methane followed by the enthalpy for methanol in kilojoules separated by a comma using four significant figures.

Natural gas is very abundant in many Middle Eastern oil fields. However, the costs of shipping the gas to markets in other parts of the world are high because it is necessary to liquefy the gas, which is mainly methane and has a boiling point at atmospheric pressure of –164 °C. One possible strategy is to oxidize the methane to methanol, CH₃OH, which has a boiling point of 65 °C and can therefore be shipped more readily. Suppose that 10.7 10⁹ ft³ of methane at atmospheric pressure and 25 °C is oxidized to methanol. (a) What volume of methanol is formed if the density of CH₃OH is 0.791 g/mL? (b) Write balanced chemical equations for the oxidations of methane and methanol to CO₂(g) and H₂O(l). Calculate the total enthalpy change for complete combustion of the 10.7 × 10⁹ ft³ of methane just described and for complete combustion of the equivalent amount of methanol, as calculated in part (a). (c) Methane, when liquefied, has a density of 0.466 g/mL; the density of methanol at 25 °C is 0.791 g/mL. Compare the enthalpy change upon combustion of a unit volume of liquid methane and liquid methanol. From the standpoint of energy production, which substance has the higher enthalpy of combustion per unit volume?
