joseph failed to calibrate the spectrophotometer. As a result, all absorbance values for the standard solutions that are measured and recorded are too high. Will the equilibrium concentration for FeNCS2+ be too high, too low, or unaffected? Explain. Will the equilibrium concentration of Fe3+ be too high, too low, or unaffected? Explain. Will the calculated equilibriumbe t constants be too high, too low, or unaffected? Explain.
