निम्न सेल अभिक्रिया \( \mathrm{Zn}+\mathrm{Cu}^{2+}=\mathrm{Cu}+\mathrm{Zn}^{2+} \) का मानक emf, \( 25^{\circ} \mathrm{C} \) पर \( 1.10 \) वोल्ट है। यदि \( 0.1 M \mathrm{Cu}^{2+} \) और \( 0.1 M \mathrm{Zn}^{2+} \) विलयनों का \( 25^{\circ} \mathrm{C} \) पर लिया जाये, तो अभिक्रिया के \( \mathrm{emf} \) का मान निम्नलिखित होगा :
(A) \( 1.10 \mathrm{~V} \)
(B) \( 0.110 \mathrm{~V} \)
(C) \( -1.10 \mathrm{~V} \)
(D) \( -1.110 \mathrm{~V} \)
