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 r

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 r

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?

Solution

The problem asks us to solve the activation energy of the reverse reaction given the activation energy and the change in enthalpy. We can simply use the equation below to relate the enthalpy and the forward activation energy to the reverse activation energy. We will set Ea as the forward activation energy and Eb for the reverse.
