For the following reaction, the equilibrium constant Kc at 298 K is 1.6×1017 Fe2+(aq)+S2−(aq)⇌FeS(s) When equal volumes of 0.06 M Fe2+(aq) and 0.2 M S2– (aq) solutions are mixed, the equilibrium concentration of Fe2+(aq) is found to be Y×10–17M. The value of Y is

Answer» For the following reaction, the equilibrium constant Kc
at 298 K is 1.6×1017
Fe2+(aq)+S2(aq)FeS(s)
When equal volumes of 0.06 M Fe2+(aq) and 0.2 M S2 (aq)
solutions are mixed, the equilibrium
concentration of Fe2+(aq) is found to be Y×1017M. The value of Y is
