Solution: The activation energy for the reactionNO2(g) + CO(g) ⟶ NO(g) + CO2(g)is Ea = 100 kJ/mol and the change in enthalpy for the reaction is ΔH = -250 kJ/mol .What is the activation energy for the reverse reaction?

Problem

The activation energy for the reaction

NO2(g) + CO(g) ⟶ NO(g) + CO2(g)

is Ea = 100 kJ/mol and the change in enthalpy for the reaction is ΔH = -250 kJ/mol .

What is the activation energy for the reverse reaction?
