What's the concentration of [FeSCN2+] using limiting
reactant theory and equation?
For each test tube solution enter the initial concentration of Fe+ and SCNthe equilibrium concentration of FeSCN2: into the ICE table given. Complete entries for the rest of the table and calculate the K value for each of the tables. The values of K should be confined to a narrow range to reflect constancy. Comment on the quality of your work in this regard and calculate the average K....

A student made solution #3 using the experimental method in this
lab, and measured an absorbance of 0.559. The starting reagents are
2.00 x 10-3 M Fe(NO3)3 and 2.00 x
10-3 M KSCN.
The amount of absorption is proportional to the concentration
of
FeSCN2+. This relationship – true for many solutions – is called
“Beer’s Law”, and has the simple equation:
A = bc
where “A” is the absorption, “b” is 5174.6 for FeSCN2+ and “c”
is molarity

Q&A CH2630 LB (5 points) Name: Given the information in Table 1 below, calculate the concentrations of each species to complete Table 2 Iron(III) nitrate and KSCN are initial concentration values, while the concentration of FeSCN is after the reaction is complete. As the concentration of Felis significantly larger than that of SCN, the reaction conditions depicted are non-equilibrium. Since there is a large excess of one reactant, the concentration of FeSCN2+ is dependent upon the limiting reactant. This is...
