A) \[1.1\,\,V\]
B) \[1.4\,\,V\]
C) \[1.34\,\,V\]
D) None of these
Correct Answer: A
Solution :
Given,\[E_{Z{{n}^{2+}}/zn}^{o}=-0.76\,\,V\] \[E_{C{{u}^{2+}}/Cu}^{o}=0.34\,\,V\] \[EMF=E_{R}^{\text{o}}-E_{L}^{\text{o}}\] \[\Rightarrow \] \[EMF=E_{C{{u}^{2+}}/Cu}^{\text{o}}-E_{z{{n}^{2+}}/Zn}^{\text{o}}\] \[\Rightarrow \] \[=0.34+0.76\] \[\therefore \] \[EMF=1.1\,\,V\]
