Question 1. (Electrochemistry) 2. Sn can displace Aut from aqueous solution. Write a balanced redox reaction, and, using the standard potential table attached, calculate the cell potential for this process. [6 marks] b. Calculate the equilibrium constant K, and Gibbs free energy, AG, for the reaction of Sn with Aut, under standard conditions. [8 marks] c. Briefly explain the differehce between outer- and inner-sphere electron transfer, with reference to the rate-determining step for electron transfer in each case. [6 marks)
