When Fe(NO3)3(aq) and KSCN(aq) were initially mixed they reacted and established an equilibrium with [Fe(SCN)]²?(aq). Write the net ionic chemical equation equation for this reaction. Calculate Q when the solutions are mixed (time zero). Indicate how the reagent concentrations will changes as the reaction proceeds.
