Abstract

In this study Metronidazole drug is used to reduce the conductivity of 0.5M hydrochloric acid at different concentrations for each one of them at different temperatures ranged (30-60)°C. Generally , at constant temperature as concentration of Metronidazole increased as the inhibition efficiency increased due to the reduced in molar conductance. On the other hand, at constant concentration for the inhibitor, as temperature increased, the inhibition efficiency increased where, in both cases the ionic mobility of the acid is reduced i.e., the molar conductance of the acid is reduced in presence of the inhibitor compared with the absence of it. i.e., Metronidazole can adsorbed chemically on the metal or alloy. Furthermore the kinetic study of the molar conductance process reveal that in presence of Metronidazole the activation energy and enthalpy of activation are negative compared with their values in absence of paracetamol where they are negative because the reducing the conductivity in presence of Metronidazole where the non spontaneous property for the conductance of acid is increased as the Metronidazole concentration increased in addition to increasing the negative value of entropy in presence of Metronidazole that indicate to restrict for the mobility of hydrogen and chloride ions which correspond to 94.38% as inhibition efficiency of reducing the conductance of acid by Metronidazole . On the other hand thermodynamic study is achieved which explained the adsorption mode of Metronidazole depend on the temperature where, different modes for the adsorption iso therms can be obtained at each temperature in this study.
