The standard EMF of a Daniel cell at \( 298 \mathrm{~K} \) is \( E_{1} \). When the concentration of \( \mathrm{ZnSO}_{4} \) is \( 1.0 \mathrm{M} \) and that of \( \mathrm{CuSO}_{4} \) is \( 0.01 \mathrm{M} \), the EMF becomes \( E_{2} \) at \( 298 \mathrm{~K} \). The correct relationship between \( E_{1} \) and \( E_{2} \) is
(a) \( E_{1}=E_{2} \)
(b) \( E_{2}=0 \)
(c) \( E_{1}E_{2} \)
(d) \( E_{1}E_{2} \)
