Question “Part E Calculate the approximate enthalpy change , ?H?, for the combustion of methane: CH4+2O2?2H2O+CO2 Use…”
Part
E Calculate the approximate enthalpy change , ?H?, for the
combustion of methane: CH4+2O2?2H2O+CO2 Use the values you
calculated in Parts A to D, keeping in mind the stoichiometric
coefficients. Please explain.
Answer
The following combustion reaction occurs: CH4 +202 geun O+ CO2 In this reaction, 4 ‘C-H’ bonds are broken and 2 ‘O-O’ bond breaks. Bond breaking is an energy-absorbing process. Energy was absorbed 4x (C-H bond energies) + 2x (O-O bond energies) Ren. + 2x Do 1640kJ/mol +2x (498kJ/mol), = 2636kJ/mol
The given reaction produces 4 O-H bonds and 2 C-O’ bonds. -663 kJ/mol
Conclusion
Above is the solution for “Part E Calculate the approximate enthalpy change , ?H?, for the combustion of methane: CH4+2O2?2H2O+CO2 Use…“. We hope that you find a good answer and gain the knowledge about this topic of science.
