How long (approximate) should water be electrolyzed by passing through amperes current so that the oxygen released can completely burn of diborane ? (Atomic weight of )?
hours
Explanation for the correct options:
B) hours
Step 1: amperes, of diborane
Step 2: Faraday's Law mass of the substance deposited during electrolysis quantity of electricity passing
Step 3: Reaction involved
of mole of which requires three moles of oxygen() for complete burning
(On electrolysis)
On electrolysis of water,
mole of is produced by charge.
Then, mole of will require charge.
Now applying,
Therefore, time taken for water to be electrolyzed is hours
Explanation for the incorrect option:
(A) The above detailed explanation clearly explains option A is incorrect.
(C) The above detailed explanation clearly explains option C is incorrect.
(D) The above detailed explanation clearly explains option D is incorrect.
Hence, option B is correct.
