Consider the galvanic cell shown below (the contents of each half-cell are written beneath each compartment) :
0.50 M Br2 0.20 M Cr3+ 0.10 M Br-
The standard reduction potentials are as follows:
Cr3+(aq) + 3e- Cr(s) =-0.73 V
Br2(aq) + 2e- 2Br-(aq) = +1.09 V
Which of the following statements about this cell is false?
A) This is a galvanic cell.
B) Electrons flow from the Pt electrode to the Cr electrode.
C) Reduction occurs at the Pt electrode.
D) The cell is not at standard conditions.
E) To complete the circuit,cations migrate into the left half-cell and anions migrate into the right half-cell from the salt bridge.
