Answer : The concentration of NaOH is, 0.336 M
Explanation:
To calculate the concentration of base, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Thus, the concentration of NaOH is, 0.336 M
Answer:
Standard free-energy change at is

--------------------------------------------------------------------------------------
Overall:
Standard cell potential,
So,
We know, standard free energy change at (
):
where, n is number of electron exchanged during cell reaction, 1F equal to 96500 C/mol
Here n = 2
So,
