A galvanic^cell consists of left ompartmcnt with a tin elcctrode in contact with 0.1 M Sn(NO_3)_2(aq) and a right compartment with a lead electrode in contact with 1 times l0^-3 M Pb(NO_3)_2(aq). The relevant reduction potentials are: When this cell is allowed to discharge spontaneously at 25 degree C, which of the following statements is true?
a) Electrons will flow from left to right through the wire.
b) Pb^2+ ions will be reduccd to Pb metal.
c) The concentration of Sn2+ ions in the left compartment will increase.
d) The tin electrode will be the cathodc.
e) No noticeable change will occur, bccausc the cell is a. eqmhbnum.
