Hello, hi students, let me explain you the question.
00:02
In this particular question, they have given some of the standard electrode potentials.
00:08
Standard electrode potentials.
00:11
So by using standard electrode potential, we have to calculate the standard cell potential, standard cell potential for the reaction.
00:22
The reaction, this reaction occurs in electrochemical cell at 25 degrees centigrade.
00:27
Electrochemical cell at 25 degrees centigrade.
00:32
The reaction is 2fe 3 plus aquaise plus 3 jaden solid.
00:38
It used rise to 2fe solid plus plus 3z2 plus.
00:45
So this is the reaction.
00:47
So whenever we observe this reaction here at anode which reaction takes place at cathode which reaction takes place.
00:57
So first of all, we have to note the standard reduction potential for standard reduction potential.
01:07
So the standard reduction potential for the first one, fe3 plus acws plus 3 electrons gives rise to fes that is equal to minus 0 .04 volts.
01:20
This is the standard reduction potential for this reaction.
01:24
And jn2 plus acws plus 2 electrons gives rise to.
01:29
Zn solid that is equal to minus 0 .76 volts...
