Question
Three common hydrocarbons that contain four carbons
are listed here, along with their standard enthalpies of
formation:
(a) For each of these substances, calculate the molar enthalpy
of combustion to CO2(g) and H2O(l). (b) Calculate
the fuel value, in kJ/g, for each of these compounds. (c) For
each hydrocarbon, determine the percentage of hydrogen
by mass. (d) By comparing your answers for parts (b) and (c),
propose a relationship between hydrogen content and fuel
value in hydrocarbons.
