The standard EMF of Daniell cell is 1.10 volt. The maximum electrical work obtained from the Daniell cell is

A

212.3kJ

B

175.4 kJ

C

106.15 kJ

D

53.07kJ

Answer

212.3kJ

Explanation

Solution

Electrical work obtained =−Wcell0max⁡= - {W{}_{cell}^{0}}_{\max}

=2×96500×(1.1)J=212300J=212.3kJ\mathbf{= 2 \times 96500 \times (1.1)J = 212300J}\mathbf{= 212.3kJ}
