The value of reaction quotient `Q` for the cell
`Zn(s)|Zn^(2+)(0.01M)||Ag^(o+)(1.25M)|Ag(s) is `

A

156

B

125

C

`(1.25xx10^(-2)`

D

`(6.4xx10^(-3)`

Text Solution

Verified by Experts

The correct Answer is:
D
Write cell reaction `Zn(s) + 2Ag^(+) (1.25M)rightarrow Zn^(2+) (9.01M) + 2A(g)`
`Q= (aZn^(2+))/((a_(Ag)^(+))^(2)) = (0.01)/(1.25)^(2)= 6.4 xx10^(-3)`
