1.	`2Ce^(4+) + Co rightarrow 2Ce^(3+) + Co^(2+), E_(cell)^(@) = 1.89V` `E_(Co^(2+)//Co)^(@) = -0.277V`. Hence `E_(Ce^(4+)//Ce^(3+))^(@)` isA. 0.805 VB. 1.62 VC. `-0.805 V`D. `-1.61 V`
Answer» Correct Answer - B `E_(cell)^(@)=1.89,E_(Ce^(4+)//Ce^(3+))^(@)+E_(Co//Co^(3+))^(@)+E_(Co//Co^(2+))^(@)=E+0.277impliesE=1.62V`
