For the formation of 1 mol of nitrosyl chloride at a given temperature,Δ_rH = -37 kJ/mol. NO(g) + ½ Cl₂(g) → NOCl(g)
The activation energy for this reaction is 81 kJ/mol.What is the activation energy for the reverse reaction?

Question

Quizplus · Accepted Answer

The activation energy for the reverse reaction can be found by adding the enthalpy change of the reaction (ΔH) to the activation energy of the forward reaction. Given ΔH = -37 kJ/mol and the activation energy for the forward reaction is 81 kJ/mol, the activation energy for the reverse reaction is 81 kJ/mol - (-37 kJ/mol) = 118 kJ/mol.
