Estimate the average S-F bond energy in SF6 The standard heat of formation values of SF6(g) , S(g) and F)(g) are: -1100, 275 and 80 kj / mol respectively.
∆H=∆Hf (products) -∆Hf(Reactants)
S(g) +6F)(g) ------>SF6(g)
The Attempt at a Solution
I found the ∆H formation of the reaction which I got -1455 kJ/ mol and taking this as my bond energy. But My answer doesn't match so can you tell me what am I doing wrong [/B]
