Bond energy of hydrogen gas is -433 kJ. ...

Bond energy of hydrogen gas is -433 kJ. How much is the bond dissociation energy of 0.5 mole of hydrogen gas?

A

`-433kJ`

B

`+433kJ`

C

`-216kJ`

D

`+216kJ`

Text Solution

Verified by Experts

The correct Answer is:
D
Bond dissociation energy=-bond formation energy given, bond energy of hydrogen =-433kJ
`therefore`Bond dissociation energy of one mole of `H_(2)=-433kJ`
`therefore`Bond dissociation energy of 0.5 mole of `H_(2)=(433)/(2)`
`=+216.5kJ`
