A galvanic cell at a temperature of
25.0°C
is powered by the following redox reaction:
→+MnO2s+4H+aq2Cr2+aq+Mn2+aq+2H2Ol2Cr3+aq
Suppose the cell is prepared with
4.79
M
H+
and
3.76
M
Cr2+
in one half-cell and
7.49
M
Mn2+
and
7.43
M
Cr3+
in the other.
Calculate the cell voltage under these conditions. Round your answer to
3
significant digits.
