A student wants to determine the maximum voltage and power output of a primary cell that consists of a zinc electrode in 1M Zn(NO3)2 solution and a silver electrode in 1M AgNO3 solution. The student knows the standard reduction potentials of Zn2+/Zn and Ag+/Ag to be -0.76V and +0.80V, respectively. Assuming the cell operates under standard conditions at 298K, what is the maximum voltage that the cell can generate and the maximum power output it can deliver?
