Question

Consider the following reaction: FE^3+ (aq) + SCN^- (aq) --->FeSCN^2+ (aq)

A 5.0 mL volume of 0.0200 M Fe(NO3)3 is mixed with 5.0mL of0.00200 M NaSCN; the blood-red [FeSCN^2+] ion forms and anequilibrium is established between reactants and products. Themolar concentration of [FeSCN^2+] measured spectrophotometricallyis determined to be 7.0x10^-4M at equilibrium.

Calculate Kc showing all work and employing an ICE table.
