For a reaction `A(s)+2B^(+) (aq) rarr A^(2+) (aq) rarr A^(2+)(aq)+2B,

1.	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")^(@)` is 0.354 VA. 0.354 VB. 0.708 VC. 0.0098 VD. 1.36 V
Answer» Correct Answer - A We know that `DeltaG^(@)=-2.303 RT log K_(C)` `=-2.303 RT log 10^(12)=-12xx2.303 RT` also `DeltaG^(@)=-nFE_("cell")^(@)` or `E_("cell")^(@)=(2.303 RT)/(nF)xx12=0.059/2xx12, (n=2) =0.354 V`
