The Nernst equation gives`……………. EMF` of the cell and in a Deniell cell current flows from `…………………` to `……………….`

Explanation

To solve the question, we need to fill in the blanks regarding the Nernst equation and the flow of current in a Daniel cell.

### Step-by-Step Solution:

1. **Understanding the Nernst Equation**:
- The Nernst equation relates the electromotive force (EMF) of a cell to the concentrations of the reactants and products involved in the electrochemical reaction.
- The general form of the Nernst equation is:
\[ E = E^\circ - \frac{0.0591}{n} \log Q \]
- Here, \(E\) is the EMF of the cell, \(E^\circ\) is the standard EMF, \(n\) is the number of electrons transferred in the reaction, and \(Q\) is the reaction quotient, which depends on the concentrations of the reactants and products.

2. **Filling the First Blank**:
- From the understanding of the Nernst equation, we can conclude that the Nernst equation gives the **concentration dependence of the EMF** of the cell.
- Therefore, the first blank can be filled as:
- "The Nernst equation gives **the concentration dependence of the EMF** of the cell."

3. **Understanding Current Flow in a Daniel Cell**:
- In a Daniel cell, oxidation occurs at the anode (where zinc is oxidized), and reduction occurs at the cathode (where copper ions are reduced).
- The flow of electrons is from the anode to the cathode. However, by convention, the flow of current is considered to be in the opposite direction to the flow of electrons.

4. **Filling the Second and Third Blanks**:
- In a Daniel cell, current flows from the **cathode to the anode**.
- Therefore, the second and third blanks can be filled as:
- "In a Daniel cell, current flows from **the cathode** to **the anode**."

### Final Answer:
- The Nernst equation gives **the concentration dependence of the EMF** of the cell and in a Daniel cell current flows from **the cathode** to **the anode**.
