How long (approximate) should water be electrolysed by passing through 100 amperes current so that the oxygen released can completely burn 27.66 g of diborane?
Text Solution
Verified by ExpertsThe correct answer is:
A
B 2 H 6 + 3O 2 ⎯→ B 2 O 3 + 3H 2 O
1 mol 3 mol
3 mol O 2 is required for Burning 1 mol B 2 H 6
H 2 O 
(V.F. of O 2 = 4)
= 3
= 3
∴ t = 
= 3.22hrs.
