In the Hall process, aluminium is produced by the electrolysis of molten `Al_2O_3`. How many second would it take to produce enough aluminium by the Hall process to make a case of 24 cans of auminium soft-drink, if each can uses 5.0g of Al, a current of 9650amp is employed and the current efficiency of the cell is 90%:

A

203.2

B

148.14

C

333

D

6.17

Text Solution

Verified by Experts

The correct Answer is:
B
No. of equivalent of aluminu, `(W)/(E)=(Exxetaxxt)/(96500)`
`(24xx5)/(27)xx3=(9650xx0.9xxt)/(96500),t=148.14sec`
