Question details
I need help with part C , I have listed the equation I got from my excel graph of absorbance vs [FeNcs2+] from part A.

Table 34.2 Composition of the set of Equilibrium Test Solutions for the Determination of K Test 0.002 M Fe (NO3 0.002 M NaSCN Solution (in 0.1 M HNO, 0.1 M HNO, 5 mL 1 mL 4 mL 5 mL 2 mL, 3 mL 5 mL 3 mL, 2 mL. 5 mL. 4 mL 1 mL 5 mL 5 mL If 0.002 M Fe(NO), is not available, dilute 1.0 mL (measure with a 1.0 ml. pipet) of the 0.2 M Fe(NO, used i with 0.1 M HNO in a 100-ml. volumetric flask and then share the remaining solution with other students. for this set of solutions is 0.002 M, not the 0.2 M solution used in Part A ar molar concentration of NaSCN in 0.002 M, not 0.001 M. Record the exact molar concentrations of the Fe(NO3)3 and NaSCN reager lutions on the Report Sheet, Part B, i e, the correct number of significant figure need Once the test solutions are prepared, proceed smoothly and methodically not hurry!) through Part B.3. 2. Recalibrate the spectrophotometer. Use the blank solution from Part A to c the calibration of the spectrophotometer. See Part A.3. 3. Determine the absorbance of the test solutions. Stir or agitate each test solu until equilibrium is reached (approximately 30 seconds). Rinse the cuvet t oughly with several portions of the test solution and fill it three-fourths full. c and dry the outside of the cuvet. Be cautious in handling the cuvets. Record absorbance of each test solution as was done in Part A.4. Disposal: Dispose of all waste thiocyanatoiron (lll ion solutions from Parts and B in the Waste Salts container. CLEANUP: nse the volumetric flasks, the pipets, and the c
