A hypothetical elecrochemical cell is shown below:
`A^(ɵ)|A^(+)(xM)||B^(+)(yM)||B^(o+)`
The emf measured is `+0.20 V`. The cell reaction is

A hypothetical electrochemical cell is shown below. A|A^(+)(xM)||B^(+)(yM)|B^(+) The e.m.g. measured is 0.20V the cell reaction is

A hyptherical electrochemical cell is given as A^(Ө)|A^+ (xM) || B^+ (yM) | B^(Ө) The emf masured is + 0. 20 V . The cell reaction is .

A hypothetical electrochemical cell is shown below ThetaPt(s)|A_(2)(1 atm)|A^(-)(xM)||B^(+)(yM)|B(s)^(o+) The emf measured is 0.30V The cell reaction is :-

For an electrochemical cell Cu//Cu^(2+) (XM)||Ag^(+) (Ym)//Ag . The cell reaction is

The e.m.f of the cell Mg(s)|Mg^(2+)(0.1M)||Cu^(2+)(1xx10^-xM)|Cu is 2.651 V. The standard e.m.f of the cell is 2.71 V. the value of x is

The e.m.f. of the cell Ti|Ti^(+)(0.001M)||Cu^(2+)(0.01M)|Cu is 0.83V the emf of this cell could b e increased by
