Faraday has the dimensions of-

Options

A. Coulombs
B. Coulomb equivalent
C. Coulomb per equivalent
D. Coulomb per degree Kelvin

Explanation

To find the dimensions of Faraday, we need to analyze its definition and the units involved.

### Step-by-step Solution:

1. **Understanding Faraday's Definition**:
- Faraday's constant (F) is defined as the amount of electric charge per mole of electrons. It is approximately equal to 96485 Coulombs per mole of electrons.

2. **Identifying the Units**:
- The unit of charge is Coulombs (C).
- The equivalent refers to the amount of substance that reacts with or produces one mole of electrons in a redox reaction.

3. **Expressing Faraday's Constant**:
- Faraday's constant can be expressed as:
\[ F = \frac{Q}{n} \]
where \( Q \) is the total charge in Coulombs and \( n \) is the number of equivalents (which is the number of moles of electrons transferred).

4. **Finding the Dimensions**:
- Rearranging the equation gives:
\[ Q = F \times n \]
- Therefore, the dimension of Faraday can be expressed as:
\[ \text{Dimension of Faraday} = \frac{\text{Coulombs}}{\text{equivalent}} \]

5. **Conclusion**:
- Thus, the dimension of Faraday is Coulombs per equivalent.

### Final Answer:
The dimension of Faraday is **Coulombs per equivalent**.
