A

is always successive (energy is released)

B

is always positive (energy is absorbed)

C

can be positive or negative

D

is always zero

Text Solution

Verified by Experts

The correct Answer is:
B
`O_((g))+e^(-) underset(-EA_(1))(rarr)O_((g))^(ɵ) + e^(-) underset(+EA_(2))(rarr) O_((g))^(2-)`
Energy is required to add an eelctron to the negatively charge species due to electron-electron repulsion.
