How much electricity in terms of Faraday...

How much electricity in terms of Faradays is required to produce 40.0 g of Al from molten `Al_2O_3` ?

A

4.47 F

B

4.44 F

C

5.45 F

D

6.43 F

Text Solution

Verified by Experts

The correct Answer is:
B
For 1 g equivalent (1.e. 27/3 g of Al) required electricity=1 F
For 40.0 g, electricity required = `1/(27//3)xx40=(40xx3)/27` =4.44 F
