Answer:
The energy need to break this 0=0 bond is 495 kJ/mol
Explanation:
Step 1: Data given
oxygen molecule = O2
In an O2 molecule, the 2 O-atoms are held together by a double bond with a bond energy of 495 kJ/mol.
To break this chemical bound, it requires energy
2O(g) → O2(g)
The bound energy of a double oxygen bound = 495 kJ/mol
Since we have 1 molecule (consisting in 2 O atoms)
The energy need to break this 0=0 bond is 495 kJ/mol
