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

64xx10^(-3)

Text Solution

Verified by Experts

The correct Answer is:
d
Write cell reaction `:`
`Zn(s)+2Ag^(o+)(1.25M)rarr Zn^(2+)(0.01M)+2Ag(s)`
`A=([Zn^(2+)])/([Ag^(o+)])=(0.1)/((1.25)^(2))=64xx10^(-3)`
