I need help with this. Here is the information and data needed.



  1. Record your slope and correlation coefficient, and intercept form your Part 1 graph


Y = Absorbance = 447.6 nm


B = Y Intercept = 0.006465


M = slope 2838



K = concentration of (FeSCN)


So (FeSCN) equilibrium is = to : 447.6 – (0.006465) / 2838 = 0.1577144239



Equation of best fit line ____________________________________________________




Part II



Table 2. Raw data collected































Solution



Temperature (°C)



Absorbance



1



Room temperature (°C)



0.223



2



Room temperature (°C)



0.330




3



Room temperature (°C)



0.448




4



Room temperature (°C)



0.543





  1. Calculate the equilibrium concentration of Fe(SCN)2+
    for each solution 1-4 using the equation from the line on your graph obtained in Part I. Enter your results in Table 3.  Show at least one sample calculation.
