For a reaction `A(s)+2B^(+) (aq) rarr A^(2+) (aq) rarr A^(2+)(aq)+2B, K_(C)` has been found to be `10^(12)`. The `E_("cell")^(@)` isA. 0.354 VB. 0.708 VC. 0.0098 VD. 1.36 V

Answer» Correct Answer - A
`E_("cell")^(@) = (0.0592)/(n) log K_(c)`
`therefore E_(cell)^(@) = (0.0592)/(2) log 10^(12) (0.0592 xx 12)/(2) = 0.354` V
