A student combines Fe(NO3)3 solution and KSCN solution to produce a solution in which the initial concentrations of Fe3+(aq) and SCN–(aq) are both 7.9 × 10–3 M. The absorbance of this solution is measured, and the equilibrium FeSCN2+(aq) concentration is found to be 1.8 × 10–3 M. Fe3+ + SCN- <=> FeSCN2+ Determine the equilibrium constant for the above reaction
