Consider the following reaction: C2H4(g) + F2(g) → C2H4F2(g) ΔH = -549 kJ. Estimate the carbon-fluorine bond energy given that the C-C bond energy is 347 kJ/mol, the C=C bond energy is 614 kJ/mol, and the F-F bond energy is 154 kJ/mol.
Added by Ronnie H.
Step 1
The energy required to break these bonds is the sum of their bond energies: Energy to break bonds in reactants = 614 kJ/mol (C=C) + 154 kJ/mol (F-F) = 768 kJ/mol Show more…
