If the heat of formation of MH(4) is -16...

If the heat of formation of `MH_(4)` is -1600 kJ, the bond energy of M-H would be :

A

1600 KJ

B

`-1600 KJ`

C

`400 KJ`

D

`-400 KJ`

Text Solution

Verified by Experts

The correct Answer is:
C
Heat of dissociation of `MH_(4)`
`DeltaH_(D)=+1600 kJ`
As, there are four M-H bonds in `MH_(4)`, bond energy of `M-H" bond "=(1600)/(4)=400 kJ`
