If values of `Delta_(f)H^(Theta)` of `ICI(g),CI(g)`, and `I(g)` are, respectively, `17.57,121.34`, and `106.96 J mol^(-1)`. The value of `I-CI` (bond energy) in `J mol^(-1)` is

A

`35.15 "J mol"^(-1)`

B

`106.69 "J mol"^(-1)`

C

`210.73 "J mol"^(-1)`

D

`420.9 "J mol"^(-1)`

Text Solution

Verified by Experts
