Problem: The "Chemistry Put to Work" box on pipelines in Section 10.5 in the textbook mentions that the total deliverability of natural gas (methane, CH4) to the various regions of the United States is on the order of 2.7 1012 L per day, measured at STP.Calculate the total enthalpy change for combustion of this quantity of methane. (Note: Less than this amount of methane is actually combusted daily. Some of the delivered gas is passed through to other regions.)

Step 1

PV = nRTn = PVRTn = (1 atm)(2.7×1012 L)(0.08206 atm·Lmol·K)(273.15 K)
