Please explain, thank you! (4) Consider a cell at 298 K in which the reaction is Pb (s)+2H (aa-Pb2+ (ag) +H2 (g) (a) Cr ions are added to the Pb|Pb2+ half-cell to precipitate PbCh. The cell voltage is then measured to be +0.210 V. If [H]-1.0 M and the partial pressure of hydrogen is 1.0 atm, what is [Pb2*]? (answer: 1.57 x 103 M) (b) Calculate the Kp of PbCh if [Cl]-0.10 M in the PblPb2 half-cell. (answer: 1.57 x...
