Question

What is the enthalpy change (in kJ/mol) for the combustion of methane, CH4(g), given the following thermochemical equation:CH4(g) + 2 O2(g) -> CO2(g) + 2 H2O(l)ΔHrxn = -890.3 kJ/mol

Answer 1

The enthalpy change  H  for the combustion of methane, CH4 g , is given in the thermochemical equation:CH4 g  + 2 O2 g  -> CO2 g  + 2 H2O l Hrxn = -890.3 kJ/molThis means that the enthalpy change for the combustion of methane is -890.3 kJ/mol.
