Modified Nernst equation:
Ag+ + e-→ Ag E° = +0.80 V
H2O2 + 2H+ + 2e-→ 2H2O E° = +1.78 V
In log function:
For the half reactions:
A galvanic cell is based on the following half-reactions at 25°C:
Ag+ + e- → Ag
H2O2 + 2H+ + 2e- → 2H2O
Predict whether Ecell is larger or smaller than E°cell for the following cases.
b. [Ag+] = 2.0 M, [H2O2] = 1.0 M, [H+] = 1.0 x 10 -7 M
