How much time is required for complete decomposition of 4 moles of water using 4 ampere?

Text Solution

Verified by Experts

The correct Answer is:
1.93
To decompose 1 mole of `H_(2)O`, we need two moles of electrons i.e. 2 faraday
To decompose 4 moles of `H_(2)O`, we need 8 faraday.
Now, `Q=i xx t rArr t=(8xx96500)/(4)=1.93xx10^(5)` sec
