Using the table of average bond energies, determine the total bond energy for the reactants in the combustion of ethene: C2H4 + 3 O2 --> 2 CO2 + 2 H2O

Using the table of average bond energies determine the total bond energy for the reactants in the combustion of ethene C2H4 3 O2 gt 2 CO2 2 H2O class=

Respuesta :

Explanation:

Hydrogen bonds with carbon 4 times, carbon bonds with itself once, and oxygen bonds with itself 3 times.

Energy of reactants:

E = 4 * 413 + 347 + 3 * 495

= 3484kJ/mol

Answer:

Energy transferred in = 3484kJ/mol
