The activation energy for the reaction NO2(g) CO(g) NO(g) CO2(g) is 125 kJ mol, and E for the reaction is 216 kJ mol What is the activation energy for the reverse reaction NO(g) CO2(g) NO2(g) CO(g)

Question: The activation energy for the reaction NO2(g) + CO(g) NO(g) + CO2(g) is 125 kJ/mol, and E for the reaction is 216 kJ/ mol.

The activation energy for the reaction NO2(g) + CO(g) → NO(g) + CO2(g) is 125 kJ/mol, and ΔE for the reaction is –216 kJ/ mol. What is the activation energy for the reverse reaction.
[NO(g) + CO2(g) → NO2(g) + CO(g)]?
