The process requiring absorption of energy is (1) F to F^(-) (2) Cl to Cl^(-) O to O^(2-) (4) H to H^(-)

The process requiring absorption of energy is (1) F to F^(-) (2) Cl t

1.	The process requiring absorption of energy is (1) F to F^(-) (2) Cl to Cl^(-) O to O^(2-) (4) H to H^(-)
Answer» SOLUTION :`O to O^(-)" (is EXOTHERMIC) but "O^(-) to O^(2-)" (is ENDOTHERMIC) and OVERALL " O to O^(2-)" (is endothermic)"`
