5. 6. 7. The next 3 questions refer to the diagram below. All cells are at standard state. Pb The voltage generated by the cell is: A) 0.76 V Zn Compartment A B) 0.13 V C) 0.89 V A) The electron flow will reverse. B) The voltage of the cell will decrease. C) The voltage of the cell will increase. Compartment B D) 0.63 V E) - 0.89 V If the zinc half-cell in compartment A was replaced with a silver half-cell and joined to the original compartment B, the change from the original cell in the diagram above, that would NOT be expected is: A) the voltage will be 0.93 V B) the lead half cell will be the anode C) silver ions will move toward the silver electrode D) the lead electrode will dissolve. E) electrons will flow from the silver to the lead electrode. Using the original electrochemical cell, if NaOH was added to the cell compartment A so that most of the Zn +2. was precipitated as Zn(OH)2: D) The voltage will become zero since most of the zinc is gone. E) There will be no change in the voltage of the cell.
