Δ H =[-2 × 413+(-2 × 328)] =[-826-656]=-1482 kJ / mol

Q. Use the bond energy data and calculate the enthalpy change for

The bond energies of $C - H$ and $C - Cl$ are $413$ and $328 k J m o l^{- 1}$ respectively.

$- 1465 k J / m o l$

$1465 k J / m o l$

$- 1482 k J / m o l$

$1482 k J / m o l$

$Δ H = [- 2 \times 413 + (- 2 \times 328)]$

$= [- 826 - 656] = - 1482 k J / m o l$
