Given below are few reactions with some expressions. Mark the expressions which is not correctly matched.

A

For concentration cell, `Ag|Ag^(+)(C_1)||Ag^(+)(C_2)|Ag, E_"cell"=-0.0591/1"log"C_1/C_2`

B

For the cell , `2Ag^(+) +H_2 "(1 atm)" to 2Ag + 2H^(+) (1M) , E_"cell"=E_"cell"^@-0.0591/2"log"([Ag^+]^2)/[H^+]^2`

C

For an electrochemical reaction, at equilibrium `aA + bB overset("ne"^-) hArr cC + dD, E_"cell"^@=0.0591/n "log"([C]^c [D]^d)/([A]^a [B]^b)`

D

For the cell , `M_((aq))^(n+) + "ne"^(-) to M_((s)) , E=E^@-0.0591/n "log"1/([M^(n+)])`

Text Solution

Verified by Experts

The correct Answer is:
B
For `2Ag^(+) + H_2` (1 atm) `to 2Ag + 2H^(+)` (1 M )
`E_"cell"=E_"cell"^@-0.0591/2"log"([H^+]^2)/([Ag^+]^2)`
