Question

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
CO21g2 and H2O1l2. Calculate the total enthalpy change
for complete combustion of the 10.7 * 109 ft3 of methanejust 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?
