Calculate Ecell for the following electrochemical cell at 25 °C
Pt(s) | Fe3+(aq, 0.100 M), Fe2+(aq, 0.040 M) || Cl–(aq, 0.50 M) | AgCl(s) | Ag(s)
given the following standard reduction potentials.
AgCl(s) + e– → Ag(s) + Cl–(aq) E° = +0.222 V
Fe3+(aq) + e– → Fe2+(aq) E° = +0.771 V
a. +1.034 V
b. –0.508 V
c. –0.555 V
d. –0.590 V
e. –1.034 V
