The activation energy for the reaction given below is 125 kJ/mol, and ΔE for the reaction is -216 kJ/mol.

NO2(g) + CO(g) NO(g) + CO2(g)

What is the activation energy for the reverse reaction [NO(g) + CO2(g) NO2(g) + CO(g)]?

1 answer

Ea reverse = Ea fwd + dH reverse
Ea reverse = 125 + (+216) = ? KJ/mol
