Hello, in this question it is related to the electrochemistry.
00:04
Here we are given a reaction that is co plus 2 plus 2 ag and it will produce the co plus 2ag plus.
00:18
Here we need to find out the value of the free energy.
00:26
So here let us see the first the oxidation and the reduction reaction.
00:33
Oxidation reaction that means the loss of electron.
00:39
Here we can see that that is this ag by losing 2 electron it gets converted into ag plus.
00:50
So 2 ag 2 ag plus and it lose the 2 electrons.
00:54
While in the case of the reduction the co plus 2 it gains the 2 electron and it gets converted to the element co.
01:05
Reduction means the gain of electron.
01:07
Oxidation always occur at the anode cell and reduction takes place at cathode.
01:17
So here, e0 value for this oxidation and for the reduction.
01:27
For the reduction it is minus 0 .28v and for the oxidation it is minus 0 .80v.
01:40
Volt it is.
01:42
So now we know that that is e not for the reaction is equal to e not cathode minus anode or we can say the reduction minus e not value for the oxidation.
01:59
So here we have minus 0 .28...
