Question

The standard emf of Daniel cell is 1.10 volt. What is the maximum electrical work obtained from Daniel cell? (F = 96500 C)

Options

• 106.15 kJ

• 212.3 kJ

• 175.4 kJ

• 57.07 kJ

Answer 1

212.3 kJ

Explanation:

\[\ce{E^0_{cell}}\] = 1.10 volt

For Daniel cell, n = 2

Electrical work done = `"nF E"_"cell"^0`

= 2 × 96500 × 1.10

= 212.3 kJ
