`100 mL` of phosphine `(PH_(3))` on hearing forms phosphorous `(P)` and hydrogen `(H_(2))`. The volume change in the reaction is

A

an increase of 50 mL

B

an increase of 110 mL

C

an increase of 150 mL

D

a decrease of 50 mL

Text Solution

Verified by Experts

The correct Answer is:
A
`underset(100mL)underset(2mL)(2PH_(3))(g)to2P(s)+underset(150mL)underset(3mL)(3H_(2))(g)`
`:.` 100 mL of `PH_(3)` gives `H_(2)=150mL`
Increase in volume `=150-100=50mL`
