    Perform a linear regression to determine the slope of the plot of Ln(A/A0) vs time that is discussed on page 16. Recall from page 12 that the slope for this plot is -k (where k is the radioactive decay constant). Input below the value for k obtained from this data set. Answer=0.0715 Note that your k value should be positive, since it is the negative of the slope. All reaction rate constants are positive values. The units for this k...

    using microsoft excel, plot the absorbance (y-axis) vs. the concentration of each FAS standard standard (in g/ml) Use the method of least squares (linear regression) to determine the slope, intercept, and correlation coefficient. Compare your slope with the literature value of 11,100 liter*mol^-1*cm^-1. You will have to convert your slope to have the same units as the literature value. Please do this unit conversion in your notebook. (FW FAS=392.13) Absorbance was read at 508 nm in a 1 cm curvette....
