Calculate `DeltaH` of the reaction, `H-underset(CI)underset(|)overset(H)overset(|)C-CI(g)rarrC(s) +2H(g) +2CI(g)`
Bond enegry for `C-H` bond and `C-CI` bond are `400 kJ` and `320kJ`, respectively.

Text Solution

Verified by Experts

`DeltaH`=Sum of bond energies of reactants
`-`Sum of bond energies of products.
`=[2xx(C-H)+2xx(C-Cl)]-0` (All the products are free atoms)
`=2xx415+2xx326`
`=830+652=1482kJ`
