When lead acid accumulator ( battery ) is dischanged , following reaction takes place.
`Pb(s) +PbO_(2)(s)+2H_(2)SO_(4)(aq.) rarr 2PbSO_(4)(s)+2H_(2)O`
If `1.25` ampere current is drawn for a period of 1930 minutes, mass of `H_(2)SO_(4)` consumed is

A

`196 g`

B

`49g`

C

`98 g`

D

`147 g`

Text Solution

Verified by Experts

The correct Answer is:
4
No of faraday electricity withdrawn `=(1.25xx1930xx60)/(96500)=1.5`
`1.5 ` mol of `H_(2)SO_(4)` consumed or `1.5xx98-147g`
