The standard \( \mathrm{EMF} \) of the cell reaction:
\( \mathrm{Zn}+\mathrm{Cu}^{+2} \rightarrow \mathrm{Zn}^{+2}+\mathrm{Cu} \) is \( 1.10 \) volt at \( 25^{\circ} \mathrm{C} \).
The \( \mathrm{EMF} \) for the cell reaction when \( 0.1 \mathrm{M} \mathrm{Cu}^{+2} \) and
\( 0.1 \mathrm{M} \mathrm{Zn}^{+2} \) solutions are used at \( 25^{\circ} \mathrm{C} \) is
(A) \( 1.10 \mathrm{~V} \)
(B) \( 0.110 \mathrm{~V} \)
(C) \( -1.10 \mathrm{~V} \)
(D) \( -0.110 \mathrm{~V} \)
