The following electrochemical cell has been set up `:`
`Pt(l)|Fe^(3+),Fe(a=1)|Ce^(4+),Ce^(3+)(a=1)|Pt(2)`
`E^(c-)._(((Fe^(3+),Fe^(2+)))=0.77V`
and
`E^(c-)._(((Ce^(4+),Ce^(3+)))=1.61V`
If an ammeter is connected between two platinum electrodes, predict the direction of the flow of current. Will the current increase or decreases with time ?

The following electrochemical cell has been set up. Pt_((I))|Fe^(3+),Fe^(2+)(c=1)||Ce^(4+),Ce^(3+)(c=1)|Pt_((II)) E_(Fe^(3+)//Fe^(2+))=0.77V and E_(Ce^(4+)//Ce^(3+))^(@)=1.61V If an ammeter is connected between the two platinum electrode, predict the direction of flow of current. Will the current increase or decrease with time ?

The following electrochemical cell has been set-up, Pt(1)|Fe^(3+), Fe^(2+) (a=1)||Ce^(4+), Ce^(3+) (a=1) Pt (2) E^(@) (Fe^(3+) //Fe^(2+))=0.77 V, E^(@) (Ce^(4+)//Ce^(3+))=1.61 V If an ammeter is connected between the two platinum electrodes, predict the direction of flow of current. Will the current increase or decrease with time ?

The following electrochemical cell is represented as : Pt(1)|Hg^(2+),Hg_(2)^(2+)(a=1)||Ce^(4+),Ce^(3+)(a=1)|Pt(2) a. If an ammeter is connected between two platinum electrodes, predict the direction of flow of current. b. Will the current decrease or increase with time? Given :E^(c-)._(2Hg^(2+)|Hg_(2)^(2+))=0.92V,E^(c-)._(Ce^(4+)//Ce^(3+))=1.61V

If E_(Fe^(2+)//Fe)^(@)=-0.440 V and E_(Fe^(3+)//Fe^(2+))^(@)=0.770 V , then E_(Fe^(3+)//Fe)^(@) is -
