The e.m.f. of a Daniell cell at \( 298 \mathrm{~K} \) is \( \mathrm{E}_{1} \).
\( \mathrm{Zn}\left|\begin{array}{c}\mathrm{ZnSO}_{4} \\ (0.01 \mathrm{M})\end{array}\right|\left|\begin{array}{cc}\mathrm{CuSO}_{4} \\ (1.0 \mathrm{M})\end{array}\right| \mathrm{Cu} \)
When the concentration of \( \mathrm{ZnSO}_{4} \) is \( 1.0 \mathrm{M} \) and that of \( \mathrm{CuSO}_{4} \) is \( 0.01 \mathrm{M} \), the e.m.f. changed to \( \mathrm{E}_{2} \). What is the relationship between \( \mathrm{E}_{1} \) and \( \mathrm{E}_{2} \) ?
(a) \( \mathrm{E}_{2}=0 \neq \mathrm{E}_{1} \)
(b) \( \mathrm{E}_{1}\mathrm{E}_{2} \)
(c) \( \mathrm{E}_{1}\mathrm{E}_{2} \)
(d) \( \mathrm{E}_{1}=\mathrm{E}_{2} \)
