4. A cell used to purify Palladium has the following reaction: PdCl(aq+Cd(s) → Pd(s) +4 Cl(aq) + Cd²+ (aq) The cell has a measured standard cell potential at 25°C of 1.03 V A. (8 points) Write the line diagram for the cell: B. (NPC 3 points) When the cell voltage drops to 0.99 V what is this change due to? i) Concentration of Cl decreases ii) Concentration of Cd ²* increases iii) Concentration of all species is 1 M iv) Concentration of PdCl.² decreases C. (6 points) Calculate the value of K at 25°C D. (6 points) Palladium is used for catalyst manufacture and is extremely expensive (spot price on 7.02.2202: $ 62,822 per kg). Calculate the value to the nearest $, of palladium deposited when a current of 0.15 A runs for 30 min through the circuit. The electrolyte is PdCl₂
