o Write the overall cell reaction for the galvanic cell given below Pt(s) I H2(9) I H*(oq) II Cl2(g)I C(aq) I Pt(s) Pt(s) + H2(g) + ataq) â Pt(s) + 2 H + (aq) + 2 Cl2(g) 2 H+(aq) + 2 a2(g) â 2 HCI(aq) H2(g) + C12(g) â 2 H+ (aq) + 2 C1-(aq) No reaction would occur because there is no salt bridge. c. d. 1 A galvanic cell consists of one half-cell that contains Ag(s) and Ag (aq), and one half-cell that contains Culs) and Cu2 (ag). What species are produced at the electrodes under standard conditions? Ag+(aq) + e--> Ag(s) Cu2+(aq) + 2 e-â Cu(s) E. = +0.80 V E. +0.34 V a. Agls) is formed at the cathode, and Cu(s) is formed at the anode. b. Ag(s) is formed at the cathode, and Cu2+ (aq) is formed at the anode. c. Cu(s) is formed at the cathode, and Ag*(aq) is formed at the anode. d. Cu2+(aq) is formed at the cathode, and Cu(s) is formed at the anode. 32 Calculate the standard cell potential for the cell reaction given below, and determine whether or not this reaction is spontaneous under standard conditions.
