Calculate E...

Question

Calculate $E^{0}$ and E for the cell $S n | S n^{2 +} (1 M) | | P b^{2 +} (10^{- 3} M) | P b, E^{0} (S n^{2 +} | S n) = - 0.14 V E^{0} (P b^{2 +} | P b) = - 0.13$ V. Is cell representation correct?

Solution

$S n ╱ {s n}^{+ 2} 1 M / / {p b}^{+ 2} (10^{- 3} M) / p b E^{0} ({s n}^{+ 2} / s n) = - 0.14 v E^{0} ({p b}^{+ 2} / p b) = - 0.13 v S n + {p b}^{+ 2} ⟼ p b + {S n}^{+ 2} E^{0} c e l = E^{0} c a t h o d e - E^{0} a n o d e = 0.13 - (- 0.14) = 0.01 E c e l = E^{0} c e l \frac{0.059}{n} log \frac{(1) (1)}{10^{- 3}} = 0.01 - \frac{0.059}{2} log 1000 = 0.01 - 0.0885 = - 0.0785 v H e r e E c e l i s n e g a t i v e S o, R e p r e s e n t a t i o m i s w r o n g$
