The potential of the cell for the reaction, `M(s)+2H^(+) (1M)rightarrow H_(2) (g) (1atm)+M^(2+) (0.1m)`' is 1.500 V. The standard reduction potential for `M^(2+)` / M(s) couple is :

A

`0.1470 V`

B

`–1.470 V`

C

`14.70 V`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`E_("Cell")=E_("Cell")^@ - (0.0591)/2 log""(0.1)/1`
`E_("Cell")^@=E_(H^(+)//H_2)^@-E_(M^(2+)//M)^@`
`E_(M^(2+)//M)^@=-1.470V`
