Question 1

The standard potential for the following galvanic cell is +0.90 V:

3 Cu2+(aq) + 2 Ga(s) ⇌ 3 Cu(s) + 2 Ga3+(aq)


Given that the standard reduction potential for the Cu2+/Cu half-cell is +0.34 V, what is the standard reduction potential for the Ga3+/Ga half-cell?
◦ +1.36 V
◦ +0.56 V
◦ -1.34 V
◦ -0.56 V

Question 2

A galvanic cell consists of a La3+/La half-cell and a standard hydrogen electrode. If the La3+/La half-cell standard cell functions as the anode, and the standard cell potential is 2.52 V, what is the standard reduction potential for the La3+/La half-cell?
◦ -2.52 V
◦ +0.84 V
◦ -0.84 V
◦ +2.52 V
