If the amount of energy requird in the process X to `X^(-)` is `-5 kJ//"mole"` then calculate how many energy is required in X to `X^(-)` process

A

`-5 kJ//"mole"`

B

`gt 5 kJ//"mole"`

C

`lt 5 kJ//"mole"`

D

`5 kJ//"mole"`

Text Solution

Verified by Experts

The correct Answer is:
B
`X overset(-5 kJ//"mole")(rarr) X^(-)`
`X^(-) underset(IP_(1))(rarr) X underset(IP_(2))(rarr) X^(+)`
`IP_(1) = 5 kJ//"mole"`
Then
`IP_(2) gt IP_(1)` (Successive ionisation potential)
