In this study, we utilized the 4-Phenylpyridine N-oxide inhibitor with different concentrations of 50 to 250ppm & its effect on the carbon steel corrosion in acid 1M HCl. The outcomes indicated that such kind of inhibitors with fine quality, proficient & competence escalated with the inhibitor concentration having a temperature of 303K. However, the increase in temperature up to 313-323K reduced the efficiency. With the usage of hydrogen evolution methods and weight loss, the energy of activation escalated due to the increased concentration of inhibitor, free adsorption energy and enthalpy energy. While, physically low concentration of adsorption and mixed type for higher concentrations.
