since the concentration of water is constant throughout the reaction it will not affect the value of equilibrium constant.
concentration of complex formed as product is 0.016 means that 0.016 moles of each component in the reactant is involved in the reaction to produce the complex .hence
equilibrium concentration of reactants are 0.025-0.016=0.009 and 0.050-0.016=0.034 respectively
we know that the equilibrium constant of a particular reaction is the ratio of product of concentration of product to the concentration of reactants
kc=(0.016*0.016)/(0.009*0.034)
=0.8366

The reaction between the compound [Fe (H2O).) (NO3)2 and Na (NSC) produces a red ferric thiocyanate complex, [Fe (H2O):(NSC)] (NO3)2. Initial concentration of [Fe (H2O).) (NO3)3 and Na (NSC) were determined to be 0.025M and 0.050M. Equilibrium concentration of [Fe (H2O)s(NSC)) (NO3)2 was determined to be 0.016M. Calculate the equilibrium, Kc.

15. The pH of a solution of ferric nitrate, Fe(NO3)3, is not 7.00. This fact is best explained by the equation: A) NO3-(aq) + H2O(1) + HNO3(aq) + OH(aq) B) Fe3+(aq) + 6 H2O(1) Fe(OH)3(aq) + 3 H30+(aq) C) [Fe(OH2)6]3+(aq) + H20(1) 3 H3O+(aq) + [Fe(OH2)5(OH)]2+(aq) D) H3O+(aq) + OH-(aq) + 2 H2O(1) E) HNO3(aq) + H2O() H30+(aq) + NO3-(aq)

In a dilute nitric acid solution, Fe3+ reacts with thiocyanate ion (SCN−) to form a dark red complex: [Fe(H2O)6]3+ + SCN− ⇌ H2O + [Fe(H2O)5NCS]2+ The equilibrium concentration of [Fe(H2O)5NCS]2+ may be determined by how dark the colored solution is (measured by a spectrometer). In one such experiment, 1.0 mL of 0.20 M Fe(NO3)3 was mixed with 1.0 mL of 9.2 ×10−3M KSCN and 8.0 mL of dilute HNO3. The color of the solution quantitively indicated that the [Fe(H2O)5NCS]2+ concentration was...

The reaction of cobalt(II) nitrate and potassium thiocyanate produces a coloured complex, [Co(SCN)4]2-(aq). The initial concentrations of the reactants after mixing (before any reaction) were 0.250 mol/L Co(NO3)2(aq) and 0.500 mol/L KSCN (aq). After 20 minutes, the absorbance of the solution was 0.825. The complex, [Co(SCN)4]2-, is the only absorbing species (ε b = 9.29 (mol/L)-1). Determine the concentration of Co2+ at equilibrium.
