Consider the following cell reaction
`Zn +2Ag^(o+)rarr Zn ^(2+)+2Ag.`
Given that
`E^(c-)._(Zn^(2+)(aq)Zn(s))=-0.76V`
`E^(c-)._(Ag^(o+)(aq)Ag(s))=0.80V`
`a.` Calculate the standard `EMF` fo the cell.
`b.` Which ion is more powerful oxidizing agent ?
`c.` Which metal is more powerful reducing agent ?

A

`x+2y`

B

`2x+y`

C

`y-x`

D

`y-2x`

Text Solution

Verified by Experts

The correct Answer is:
c
`E^(c-)._(cell)=(E^(c-)._(red))_(c)-(E^(c-)._(red))_(a)`
