To solve the problem, we need to analyze the electrochemical cell given: \( \text{Zn} | \text{Zn}^{2+} (1M) || \text{Cu}^{2+} (1M) | \text{Cu} \). The cell potential is given as 1.1 V, and we need to determine the direction of electron flow when an external potential is applied. ### Step-by-Step Solution: 1. **Identify the Components of the Cell:** - The cell consists of two half-cells: - Anode: \( \text{Zn} | \text{Zn}^{2+} \) - Cathode: \( \text{Cu}^{2+} | \text{Cu} \) ...

Write down the half cell reactions and cell reaction for Daniell cell. Zn(s)|Zn^(2+)(aq)(1M) || Cu^(2+)(aq)(1M)/Cu(s)

Assertion (A): For a Daniell cell : Zn|Zn^(2+)||Cu^(2+)|Cu with E_(cell)=1.1V , the application of opposite potential greater than 1.1V results into the flow of electron from cathod to anode.
