Vedclass · Answer

(D) The bond energy depends on the bond length. As the size of the central atom increases, the bond length increases, and the bond energy decreases.The order of atomic size is $N Therefore, the order of bond energy is $N-H > P-H > As-H$.The bond energy values are $N-H = 389 \ kJ \ mol^{-1}$, $P-H = 318 \ kJ \ mol^{-1}$, and $As-H = 247 \ kJ \ mol^{-1}$.Thus, the bond energies for $P-H$, $As-H$, and $N-H$ are $318, 247, 389$ respectively.

The bond energies (in $kJ \ mol^{-1}$) of $P-H$, $As-H$, and $N-H$ are respectively:
