Problem- One of the standard solution had an abnormally low absorbance reading, causing a less positive slope for the data plot.

(1) Will the equilibrium concentration of FeNCS^2+ in the test solution be too high or too low? Explain.

(2) Will the calculated Kc for the equilibrium be too high or too low or unaffected by the erred data plot? Explain.

How do I yet start setting this up? Thank you
