Question: Given these initial concentrations: [ SCN ] = 0.000655 M, [ Fe 3 + ] = 0.000515 M, and [ Fe ( SCN ) 2

Given these initial concentrations: [SCN]=0.000655 M, [Fe3+]=0.000515 M, and [Fe(SCN)2+]=0.000000 M, determine the value for K if the [Fe(SCN)2+] at equilibrium is 0.0000865 M.

What is the value for K ?
