Phosphine (PH(3)) decomposes to produce ...

Phosphine `(PH_(3))` decomposes to produce vapours of phosphorus and `H_(2)` gas. What will be the change in volume when 100mL of phosphine is decomposed?

A

`+50mL`

B

`500mL`

C

`+75mL`

D

`-500mL`

Text Solution

Verified by Experts

The correct Answer is:
C
`4PH_(3)(g)rarrP_(4)(g)+6H_(@)(g)`
`4mLrarr1mL 6mL`
`100mLrarr(100)/(4) (6)/(4)xx100`
`100mAL rarr25mL 150mL`
Volume increases by 75 mL.
