`1 gH_(2)` gas `STP` is expanded so that the volume is doubled. Hence, work done is

A

`-22.4 L` atm

B

`-11.2 `L atm

C

`-144.8 ` L atm

D

`-1.12 L` atm

Text Solution

Verified by Experts

The correct Answer is:
B
`W=-P Delta V = - P(V_(2)-V_(1))`
`V_(1)=` volume of 1 g ( or `1//2)` mol ) `H_(2)` gas at STP `=11.2 L`
`V_(2)=2xx 11.2 L =22.4 L`
`P=1 ` atm
`:. W=- ( 22.4 -11.2)`
`=- 11.2 L` atm
