Subject: Physical Chemistry · Chapter: Electrochemistry · Topic: Electrochemistry – General · Exam: JAM 2001-2022 · Marks: 2 · Difficulty: Medium
A concentration cell with two hydrogen electrodes at two different pressures is depicted as \[ \mathrm{H_2(g)(Pt)}\;\; p_{\mathrm{H_2}}=p_1 \;\Big|\; \mathrm{HCl(aq)} \;\Big|\; \mathrm{H_2(g)(Pt)}\;\; p_{\mathrm{H_2}}=p_2 \]
The potential ($\mathrm{E_{cell}}$) of the cell is (a)$\dfrac{\mathrm{RT}}{\mathrm{F}} \ln \dfrac{p_2}{p_1}$
(b)$\dfrac{\mathrm{RT}}{\mathrm{F}} \ln \dfrac{p_1}{p_2}$
(c)$\dfrac{\mathrm{RT}}{2\mathrm{F}} \ln \dfrac{p_2}{p_1}$
(d)$\dfrac{\mathrm{RT}}{2\mathrm{F}} \ln \dfrac{p_1}{p_2}$
