Determine the equilibrium constant, Kc, for the reaction between iodine and thiosulfate ions in aqueous solution, given the initial concentrations of iodine (0.02 M), thiosulfate (0.05 M), and hydrogen ions (0.1 M). The reaction is as follows:I2(aq) + 2S2O3^2-(aq) + 2H+(aq) ⇌ 2I^-(aq) + S4O6^2-(aq) Assume that the reaction takes place at 25°C and that the reaction quotient Qc has a value of 0.04 at equilibrium.
