The quantity of electricity : 2 Faraday = 193000 Coulomb
<h3>Further explanation</h3>Given
2 moles of electrons
Required
The quantity of electricity
Solution
According to Faraday, the amount of current flowing in the electrolysis cell is closely related to the amount of substance that reacts
1 Faraday is the amount of electricity that is passed in the electrolysis cell to obtain 1 mole of electrons. 1 mole of electrons is equivalent to an electric charge of 96500 Coulombs.
The conversion / relationship can be stated as follows:
1 Faraday = 1 mole of electrons = 96500 Coulombs
1 faraday = coulomb / 96500
Can be formulated
Coulomb = Q = I. t so:
so for 2 moles electrons :
= 2 x 96500 C
= 193000 C
= 2 Faraday
Explanation:
dU=TdS-pdV (given)
To prove = 1) (at constant U)
2) (at constant V)
Solution: 1)
dU=TdS-PdV
Derivative of constant is zero.
Given that internal energy is ,U = constant
(hence proved)
Solution: 2)
dU=TdS-PdV
Differentiating with respect to dU, we get:
Derivative of constant is zero.
Given that volume is constant , V= constant
(hence proved)
