Question

In your lab, Concentration and Temperature Effects on Equilibrium, you examined the following equilibrium:

Fe³⁺ + SCN ^- D FeSCN²⁺

(yellow) (colorless) (red)

After adding Fe(NO₃)₃ to a solution at equilibirum, which of the following statements is true?

A.	The color in the test tube became a deeper red color because the equilibrium shifted to the left
	B.	The color in the test tube became a lighter color because the equilibrium shifted to the left
	C.	The color in the test tube became a lighter color because the equilibrium shifted to the right
	D.	The color in the test tube became a deeper red color because the equilibrium shifted to the right
	E.	No change in the color or equilbrium is observed.
