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)
° = -0.733 V
Br2(aq) + 2e- 2Br-(aq)
° = +1.090 V
What is the value of for this cell at 25°C?
A) 1.759 V
B) 1.823 V
C) 1.837 V
D) 1.887 V
E) 2.207 V
