Question: Consider the reaction: A solution is made containing an initial [Fe 3 + ] of 1.0 * 10 -3 M and an initial [SCN

Consider the reaction:

A solution is made containing an initial [Fe^{3 +} ] of 1.0 * 10^-3 M and an initial [SCN^–] of 8.0 * 10^-4 M. At equilibrium, [FeSCN^{2 +} ] = 1.7 * 10^-4 M. Calculate the value of the equilibrium constant (K_c).

Fe+ (aq) + SCN (aq) FeSCN+ (aq)
