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.

Consider a reaction where Ag is oxidized to Ag+ ions in a solution containing AgNO3. We set up an electrochemical cell with a Ag/Ag+ electrode as the anode and a platinum electrode as the cathode. The standard electrode potential for the Ag/Ag+ electrode is +0.80 V. What is the overpotential required to achieve a current of 2 A if the applied voltage is 1.00 V?
