The half cell reaction, with its standard reduction potentials are I) Pb^(2+) + 2Ag to 2Ag^(+) + Pb (E^(0) = -0.13V) II) Ag^(+) + e^(-) to Ag(E^(0) = + 0.80 V) Which of the following reactions will occur ?

Answer»

`PB^(2+) + 2AG to 2Ag^(+) + Pb`
`Pb^(+) + H_2 to 2H^(+) + Pb`
`2H^(+) + 2Ag to 2Ag^(+) + H_2`
`2Ag^(+) + Pb to Pb^(2+) + 2Ag `
