The temperature has a major effect on the decreasing anticorrosion activity of an inhibitor( organic component, essential oil...).
What is the mechanism happening between my substrate (mild steel) and my inhibitor (essential oil) in an aggressive medium (acid) with increasing the temperature effect?
I want to know what happens exactly on the surface of the substrate (interaction, mechanism, chemical reaction,...).
Dear Dr. Ayoub Najem ,
the inhibition efficiency decreases with increasing temperature can be due to increased rate of dissolution process of mild steel and partial desorption of the inhibitor from the metal surface with temperature (Blaedel and Meloche, 1963).

Dear Dr. @pierluigi Traverso,
Your contribution is highly recommended. I recognize your continued effort to the RG community.
Thank you,
I wish to thank ,Pierluigi Traverso . for sending me a message to call my attention to this fascinating and intriguing research investigation, which seems to parallel the kind of experimentation performed by Albert Einstein when he discovered the existence of photons when he observed the affect of exactly and precisely what happens when sunlight strikes a metal surface, that is, an electron is ejected and a photon is generated in the emission of light.
I send to Ayoub Najem my best regards and wish for progress in all scientific research endeavors.
