question 49

Multiple Choice

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^- $\to$ Cr(s) $\varepsilon$ ^$\circ$ =-0.73 V
Br₂(aq) + 2e^- $\to$ 2Br^-(aq) $\varepsilon$ ^$\circ$ = +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.
