Question

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?

(Atomic weight of $$B=10.8 u$$)


A
3.2 hours
loader
B
1.6 hours
loader
C
6.4 hours
loader
D
0.8 hours

Solution

The correct option is B 3.2 hours
$$B_2H_6 +3O_2 \rightarrow B_2O_3 + 3H_2O$$

Moles of $$O_2$$ required $$= 3 \times$$ moles of $$B_2H_6$$

$$\dfrac{I\times t}{96500} = $$ moles of $$O_2$$ $$\times 4$$

$$t = 3.2 hrs$$

So, the correct option is $$A$$
