The heats of combustion methane and carbon monoxide

With the use of the calorimetric apparatus and procedure employed for deter- mining the heat of formation of water (v.supra p. 1), the heats of combustion of methane and carbon monoxide have been measured.The heat of combustion of CH 4 to form liquid H 2 and gaseous CO2 is found to be 889,700 ±300 international joules per mole at 30° C. and a constant pressure of 1 atmosphere, which is equivalent to 890, 160 ±300 international joules per mole at 25° C. and 1 atm.The heat of combustion of CO to form C02 is found to be 282,925 ± 120 inter- national joules per mole at 30° C. and a constant pressure of 1 atm., which is equivalent to 282, 890 ±120 international joules per mole at 25° C. and 1 atm.For comparison with the older work, see Figures 1 and 2.
