For the following reaction, the equilibrium constant K_c at 298 K is 1.6 10^ 17 . Fe^ 2+ (aq)+ S^ 2- (aq) FeS (s) When equal volumes of 0.06 M Fe^ 2+ (aq) and 0.2 M S^ 2- (aq) solutions are mixed, the equilibrium concentration of Fe^ 2+ (aq) is found to be Y 10^ -17 M. The value of Y is _____

JEE Advanced 2019 Chemistry question

For the following reaction, the equilibrium constant at 298 K is .

\mathrm{}(aq)+\mathrm{}(aq)FeS(s)

When equal volumes of 0.06 M and 0.2 M solutions are mixed, the equilibrium concentration of is found to be M. The value of Y is

Answer: 8.93

After mixing equal volumes the concentrations are halved: M, M. is very large, so the reaction goes almost to completion with as the limiting
