A standard solution of FeSCN²+ is prepared by combining 9.0 mL of 0.20 M Fe(NO,), with 1.0 mL of 0.0020 M KSCN. The equation for the reaction is as follows. Fe(NO,), + KSCN= FESCN²+ + KNO, + 2 NO, What allows us to assume that the reaction goes essentially to completion? The concentration of Fe(NO,), is much higher than the concentration of KSCN. The reaction quotient Q is greater than Kç. O The equlibrium reaction has a very high K̟. The excess Fe³+ prevents the formation of the neutral Fe(SCN),. Under the conditions given, Le Châtelier's principle dictates that the reaction shifts to the left. Based on that assumption, what is the equilibrium concentration of FeSCN²+?
