2.00x10-3 M Fe3+ ion and 2.00 x 10-3 M SCN- ion stocksolutions were used to prepare the equilibrium mixtures indicatedin the table below.

Here's what I have so far:

initial Fe3+ ion concentrations of E2, E3, E4 is 1.00 x 10-3

initial SCN- ion concetrations of E2: 2.00 x 10-4, E3: 6.00 x 10-4,E4: 1.00 x 10-3

%T of E2: 72.9, E3: 43.2, E4: 32.5

absorbance of equilibrium mixtures: E2: 0.137, E3: 0.365, E4:0.488

I need helpcalculating the final equilbirium molar Fe3+ and SCN- ionconcentration, mol L-1, and Calculating the equilibrium constant,Keq for solutions E2, E3,E4.
