Mark the false statement?
(a) A salt bridge is used to eliminate liquid junction potential
(b) The Gibbs free energy change, \( \Delta \mathrm{G} \) is related with electromotive force \( \mathrm{E} \) as \( \Delta \mathrm{G}=-\mathrm{nFE} \)
(c) Nernst equation for single electrode potential is \( \mathrm{E}=\mathrm{E}^{\mathrm{o}}-\frac{\mathrm{RT}}{\mathrm{nF}} \log _{\mathrm{a}} \mathrm{M}^{\mathrm{n}+} \)
(d) The efficiency of a hydrogen-oxygen fuel cell is \( 23 \% \)
