Nyctanthes arbor-tristis (Naf) (Night flowering jasmine or Parijat) was investigated as a corrosion inhibitor for mild steel in an hydrochloric acid solution. The results revealed that the order of reaction is 0.374, with activation energy found to be 10.27 kJ/mol. Nyctanthes arbor-tristis (Naf) was effective in increasing the inhibition efficiency for all inhibition concentrations. The corrosion rate profile was found to be second- order kinetics with respect to corrosion activity.
