Final answer:
The minimum energy needed to break 1 oxygen-oxygen bond in ozone is 1548 kJ/mol.
Step-by-step explanation:
The minimum energy needed to break down an oxygen-oxygen bond in ozone, O3, is 387 kJ/mol. To determine the amount of energy needed to break 1 oxygen-oxygen bond in ozone, we need to consider the energy changes on both the reactant and product sides of the equation.
On the reactant side, there are 4 oxygen-oxygen bonds, so the total energy required to break these bonds is 4 x 387 kJ/mol = 1548 kJ/mol.
Therefore, the amount of energy needed to break 1 oxygen-oxygen bond in ozone is 1548 kJ/mol.
