The investigation of kinetics and thermodynamic of the corrosion of mild steel in 2 M HCl solution using methanolic extract of Erigeron floribundus was carried out using gravimetric techniques. The results obtained indicated that the extract retarded the corrosion of mild steel in 2 M HCl solution. The inhibition efficiency increases with increase in concentration of the inhibitor and increase in temperature. The values of activation energy (Ea) obtained indicated chemisorptions mechanism whereas the value of Gibb free energy (ΔGoads) indicated a spontaneous adsorption of the extract components on the metal surface. Kinetic modeling of the experimental data obeyed first order reaction. The adsorption of methanolic extract of Erigeron floribundus onto the mild steel surface followed Langmuir adsorption isotherm model. Therefore the extract functioned as good corrosion inhibitor for mild steel in hydrochloric acid.
