The equilibrium position will be determined by the, The equilibrium position will NOT be effected by the addition of. Once equilibrium has re-established itself, the value of Keq will be unchanged. The concentration of SCN (aq) will decrease [SCN] as . Reserve one as a reference. Since Fe3+ is on the reactant side of this reaction, the rate of the forward reaction will increase in order to "use up" the additional reactant. In 1884, the French Chemist Henri Le Chatelier suggested that equilibrium systems tend to compensate for the effects of perturbing influences (or disturbances). density of water. The addition of more Fe 3+ and SCN - causes the equilibrium to shift in favor of the products and more of the complex is formed, turning the solution to a deeper red (this indicates that free SCN - and Fe 3+ ions were present in the solution). Let's remove SCN- from the system (perhaps by adding some Pb2+ ionsthe lead(II) ions will form a precipitate with SCN-, removing them from the solution). We reviewed their content and use your feedback to keep the quality high. Write the $\ce{[FeSCN^2+]_\text{equil}}=\pu{6.39e5 M}.$, $$\ce{[Fe^3+]_\text{equil}} = \ce{[Fe^3+]_\text{initial}} - \ce{[FeSCN^2+]_\text{equil}} $$, $$ = \pu{1.00e-3 M} - \pu{6.39e5 M} = \pu{0.94e-3 M}$$, $$\ce{[SCN-]_\text{equil}} = \ce{[SCN-]_\text{initial}} - \ce{[FeSCN^2+]_\text{equil}} $$, $$ =\pu{0.400e-3 M} - \pu{6.39e5 M} = \pu{0.336e-3 M}$$.
