59. A galvanic cell consists of a left compartment with a tin electrode in contact with 0.1 M Sn(N03)2(aq) and a right compartment with a lead electrode in contact with 1 ✖ 10 -3M Pb(NO3)2(aq). The relevant reduction potentials are:   When this cell is allowed to discharge spontaneously at 25°C, which of the following statements is true?
(A) Electrons will flow from left to right through the wire.
(B) Pb2+ ions will be reduced to Pb metal.  
(C) the concentration of Sn2+ ions in the left compartment will increase.
(D) The tin electrode will be the cathode.
(E) No noticeable change will occur, because the cell is at equilibrium.
