Hello, hi students, let me explain you the question.
00:02
Here we have to calculate cell potential.
00:05
So here we have to calculate cell potential of the following working voltaic cell.
00:13
So the voltaic cell here the reaction zn, zn 2 plus 1 into 10 to the power of minus 4 molar.
00:23
Copper 2 plus 1 in 2 10 to the power of minus 6 molar is copper.
00:29
Okay so here z n2 plus reduction potential it is given as reduction jdn 2 plus reduction potential is equal to 0 .76 volts it is negative symbol minus 0 .76 volts then c u plus 2 reduction potential so c u plus 2 reduction potential that is equal to plus 0 .337 volts so the nernest equation here it is given as nernest equation.
01:04
So the nernest equation is equal to e minus 0 .0592 divided by n into log q.
01:14
Okay, this is the nernest equation.
01:17
So the voltage cell, it is nothing but electrochemical cell.
01:22
So electrochemical cell.
01:24
So in this particular voltage cell, by using chemical reaction, by using chemical reactions, they produce electrical.
01:32
Energy so that is the voltaic cell okay electrical energy and the cell potential so the cell potential of electrochemical cell it is nothing but what is cell potential it is the potential difference so it is the potential difference so this particular potential difference it occurs between electrodes that is two electrodes of the cell that is anode and cathode anode and cathode and and cathode.
02:03
So, how this particular potential difference occurs means due to the transfer of electrons due to the transfer of electrons through external circuit...
