Question
Consider the reaction from the previous question
F+SCN(g) →→→ FeSCN2
(aq)
Initially [Fe³+] = 0.00060M, [SCN1,-0.00053M. [FeSCN2+] is determined by measuring the absorbance at 450 nm. Beer's Law
for this system at 450 nm is
A=3806M-¹ [FeSCN²+ ]
Use your answer from the last question to construct an ICE table and calculate K, give the answer to two significant figures
