Subject: Physical Chemistry · Chapter: Electrochemistry · Topic: Nernst Cells · Exam: NET JUNE 2012 · Marks: 2 · Difficulty: Medium

The correct Nernst equation for the concentration cell:
\[ \mathrm{Pt}\left|\mathrm{H}_{2}(\mathrm{p})\right| \mathrm{HCl}\left(a_{ \pm}\right)_{1}|\mathrm{AgCl}(\mathrm{s})| \mathrm{Ag} \| \mathrm{Ag}|\mathrm{AgCl}(\mathrm{s})| \mathrm{HCl}\left(a_{ \pm}\right)_{2}|\mathrm{H}(\mathrm{p})| \mathrm{Pt} \]
without liquid junction would be
(a)$\mathrm{E}=\frac{2 R T}{F} \ln \frac{\left(a_{ \pm}\right) 1}{\left(a_{ \pm}\right) 2}$
(b)$\mathrm{E}=\frac{2 R T}{F} \ln \frac{\left(a_{ \pm}\right) 2}{\left(a_{ \pm}\right) 1}$
(c)$\mathrm{E}=\frac{R T}{F} \ln \frac{\left(a_{ \pm}\right) 2}{\left(a_{ \pm}\right) 1}$
(d)$\mathrm{E}=\frac{R T}{2 F} \ln \frac{\left(a_{ \pm}\right) 2}{\left(a_{ \pm}\right) 1}$
