Let's solve the question.
00:01
So delta g naught is equal to minus n, which is the number of electrons transferred for the reaction multiplied by the faraday's constant multiplied by e naught, which is the standard tell potential now the half reaction the first half reaction will be z n 2 positive in the aqueous state plus 2 electrons.
00:32
It gives z n in the solid state here.
00:35
The value of e naught is minus 0 .76 volts.
00:40
Now, the second half reaction is 2 h positive in the aqueous state plus 2 electrons.
00:48
It gives hydrogen in the gaseous state and here the value of e naught is 0 volts since it is often used as a reference.
00:59
Now, we have to calculate for the e naught self.
01:03
So the formula will be e naught of cathode minus e naught of anode so we plug in the values.
01:16
It will be minus 0 .76 volts minus 0 volts...
