## Description and Analysis of the Beer’s Law PlotA student collects absorbance versus concentration data for the thiocyanatoiron(III) complex at 510 nm and constructs a Beer’s Law plot. ### Graph Explanation- **Axes**: - The x-axis represents the concentration (M) of the thiocyanatoiron(III) complex. - The y-axis represents the absorbance.- **Trend Line**: - The plot shows a straight line that fits the data points. - The equation of the line is \( y = 15927x \). - The \( R^2 \) value is 0.9991, indicating an excellent fit with the data.### Calculation TaskFor a solution with an absorbance of 0.280 at 510 nm, determine the concentration of \([ \text{Fe(SCN)}^{2+} ]\).Using the equation of the line:\[y = 15927x\]Substitute \( y = 0.280 \):\[0.280 = 15927x\]Solving for \( x \) (the concentration):\[x = \frac{0.280}{15927}\]\[x \approx 1.76 \times 10^{-5} \, \text{M}\]Therefore, \([ \text{Fe(SCN)}^{2+} ] = 1.76 \times 10^{-5} \, \text{M}\).
