The bond energy of `H_(2)` is `104.3 kcal mol^(-1)` . If means that `:`

Options

A. `104.3 kcal `heat is needed to break up `'N'` bonds in `N` molecules of `H_(2)`.
B. `104.3 kcal ` heat is needed to break up `6.023xx10^(23)` molecules into `1.2046xx10^(24)` atoms of `H`
C. `104.3 kcal` heat is evolved during combination of `2N` atoms of `H` to form `N` molecules of `H_(2)`.
D. all of these

Answer

D

Explanation

Bond energy is the amount of heat required `//` evolved to break `//` form 1 mole bond.
