Weight-loss corrosion technique was employed in obtaining the corrosion penetration rate using the equation: cpr = \"\". Subsequently, the quadratic models were developed by using a computer-aided statistical modeling technique (International Business Machine (IBM)¡¯s SPSS version 17.0). The results obtained showed a nearly perfect positive correlation with a correlation coefficient in the range of 0.986 ¡Ü R ¡Ü 0.996 which depicts that R ¡Ý 1. Also, the coefficient of determination fell within the range of 0.972 ¡Ü R2 ¡Ü 0.992 showing that approximately 97% to 99% of the total variation in passivation rate was accounted for by corresponding variation in exposure time, leaving out only between 3% and 1% to extraneous factors that are not incorporated into the model equations. The equations were further unified into a generalized form using MathCAD 7.0 and the resulting equation was y = 1.032 £­ 0.002t + 1.899 ¡Á 10-6t2 with a R2 value of 0.935 indicating a well-correlated relationship. With this, a new frontier on corrosion studies has emerged typifying a classical departure from previously long-held assumption that corrosion behaviours at room temperature were only logarithmic. %K Corrosion %K Inhibition %K Ocimum Basilicum %K Correlation %K Quadratic Models %K Passivation %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=40091
