The potential of the cell for the reaction M_((s))+2H^(+)(1M)toH_(2(g)),(1atm)+M^(2+)(0.1M) is 1.500 V. the standard reduction potential for M^(2+)//M_((s)) couple is:-

Answer»

0.1470V
1.470V
14.70V
None of these

Solution :`E_(cell)=E_(cell)^(o)=-(0.0591)/(2)LOG((["products"])/(["REACTANTS"]))`
`1.5=E_(cell)^(@)-0.0296log[(0.1)/(1)]`
`E_(Cell)^(o)=1.470V`
`E_(Cell)^(o)=E_(H^(+)//H_(2))^(o)-E_(M//M^(2+))^(o)`
`E_(M//M^(2+))^(o)=-1.470`
So, `E_(M^(2+)//M)^(o)=1.470V`.
