Question

Calculate Ecell for the following electrochemical cell at 25 C
Pt(s) | H2(g, 1.00 atm) | H+(aq, 1.00 M) || Sn2+(aq, 0.350 M), Sn4+(aq, 0.020 M) | Pt(s)
given the following standard reduction potentials.
Sn4+(aq) + 2 e- Sn2+(s) E = +0.15 V
2 H+(aq) + 2 e- H2(g) E = 0.00 V
A.-0.19 V
B.+0.08 V
C.+0.11 V
D.+0.19 V
E.+0.22 V
