Use the reaction and bond information to answer the question.
C2H6 → C2H4 + H2
Reactant bond energies: H–C = 413 kJ/mol, C–C single bond = 347 kJ/mol
Product bond energies: H–C = 413 kJ/mol, C=C double bond = 614 kJ/mol, H–H = 432 kJ/mol
Reactions often do not occur spontaneously (without the addition of energy) if it takes more energy to start the reaction than is released at the end. Based on the bond energies, would this reaction occur spontaneously? Why or why not?
No, because the reaction is exothermic.
Yes, because the reaction is exothermic.
Yes, because the reaction is endothermic.
No, because the reaction is endothermic
