6. Give the balanced full reaction and calculate the E° for galvanic cells based on the
following reactions. Draw diagrams indicating; the anode, cathode, flow of electrons,
salt bridge
(a) Zn^2 (aq) + 2e- = Zn(s)
Pb²(aq) + 2e- → Pb(s)
(b) Cr2O7 + 14H + 6e- 2Cr³+ 7H₂O
H₂O2 + 2H+ + 2e- →2H₂O

Electrochemical cell is one in which energy is released by a chemical action.

What is an electrochemical cell?

An electrochemical cell is one in which energy is released by a chemical action.

Now we have the reaction;

Zn^2 (aq) + 2e- = Zn(s)

Pb²(aq) + 2e- → Pb(s)

and

Cr2O7 + 14H + 6e- 2Cr³+ 7H₂O

H₂O2 + 2H+ + 2e- →2H₂O

In the first case, the Ecell is obtained from;

(-0.13 V) - (-0.76 V)

= 0.63 V

In the second case;

1.78 V - 1.33 V

= 0.45 V
