Answer:
Ea = 210.5kJ/mole
Explanation:
When the reaction:
O3 + NO → O2 + NO2
Occurs, requires 10.7kJ/mole and releases -199.8kJ/mole.
For the forward reaction:
O2 + NO2 → O3 + NO
The Ea is the sum of Ea of the forward reaction and – ΔH, that is:
Ea = Ea – (-ΔH)
Ea = 10.7kJ/mol – (-199.8kJ/mol)
Ea = 210.5kJ/mole
