Use Table 9.4 to calculate an approximate enthalpy or heat of reaction for the combustion of one mole of methane gas (CH4) to form gaseous H2O and CO2. What Volume (in L) of methane is needed to produce 3287 kJ of heat for methane gas at 11 oC and 3.40 atm pressure?

Answer 1

determine z as in the previous question for the reaction CH4 + O2 --> CO2 + H2O.
z kJ/mol CH4 x # mols CH4 = 3287 kJ. Solve for # mols CH4.
Then use PV = nRT and solve for V at the conditions listed.
# mols CH4
