Question

Write nearest equation for a Daniel cell ( assume actively of metals is unity )

Answer 1

Answer:

Nernst’s Equation for Daniells Cell

Daniell’s cell consists of zinc and copper electrodes. The electrode reactions in Daniell’s cell are,

At anode :  

At cathode :  

Net cell reaction :  

Therefore, the Nernst equation for the Daniell’s cell is,

Since, the activities of pure copper and zinc metals are taken as unity, hence the Nernst equation for the Daniell’s cell is,

The above eq. at 298 K is,

For Daniells cell,
