Endgame review packet, question 2b

Postby ramiro_romero » Fri Mar 13, 2020 1:32 pm

For question 2b, I got E cell = 1.17V. delta G = -226 kJ/mol. and for K I got 91.1. I just want to make sure these answers correlate with what my peers got.

For E cell, I got 2.05 V because the Ce is the cathode and Fe is the anode so it will be 1.61V - (-0.44V) = 2.05V. Since my E cell is different than yours, I also got a different delta G and K. For delta G, I got -396 kJ/mol and for K I got 2.6 x 10^69

Thank you! What I did was I reversed the half-reaction for Fe and changed the sign of its cell potential. So I did (1.61V) - (+0.44V) to get 1.17v for the cell potential.
