A chemist designs a galvanic cell that uses these two half-reactions:
standard reduction
half-reaction
2H₂O(1)+2e
Write a balanced
equation for the
half-reaction that
happens at the
anode.
Ered=
Br₂(1)+2e
Ered = +1.065 V
Answer the following questions about this cell.
Write a balanced
equation for the
half-reaction that
happens at the
cathode.
Write a balanced
equation for the
overall reaction.
that powers the
cell. Be sure the
reaction is
spontaneous as
written.
Do you have
enough
information to
calculate the cell
voltage under
standard
conditions?
If you said it was
possible to
calculate the cell
voltage, do so and
