Question
The following electrochemical cell has been set up: Pt(s)|Fe3+, Fe2+ (a = 1)||Ce4+, Ce3+ (a = 1)|Pt(s); E°(Fe3+|Fe2+) = 0.77 V; E ° (Ce4+|Ce3+) = 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?
Options
A.Ce electrode to Fe electrode, decrease
B.Ce electrode to Fe electrode, increase
C.Fe electrode to Ce electrode, decrease
D.Fe electrode to Ce electrode, increase
Solution
Current flow from right electrode to left electrode in external circuit.
