Webintercept equal to ln(A0) for a first order reaction. Lastly, substituting absorbance values into equation 9 gives: 1/At = (k/εl)t + 1/A0 Eq. 16 where a plot of 1/At versus t gives a straight line with a slope equal to k/εl and a y-intercept of 1/A0 for a second order reaction. A correction must be introduced at this point. When the reaction ...
