Question

would you expect the second electron gain enthalpy of o as positive more negative or less negative than the first? justify your answer​

Answer 1

Answer:

Explanation:

hence, first electron gain enthalpy of oxygen is negative . But when another electron is add to O- ion to form O2- ion , it feels stronger electrostatic repulsion. hence, when we add 2nd electron , then energy absorb by it. that's why the 2nd electron gain enthalpy of oxygen is positive.
