Two moles of an ideal gas are allowed to...

Two moles of an ideal gas are allowed to expand from a volume of 10 `dm^(3)` to `2m^(3)` at 300 K against a pressure of 101.325 kPa. Calculate the work done.

A

`-201.6` kJ

B

`13.22` kJ

C

`-810` J

D

`-18.96` kJ

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(1) = 10 dm^(3) = 10p^(-2) m^(3)`
`V_(2) = 2m^(3)`
P=`101.325 xx 10^(3)` Pa
`W= P DeltaV = -101. 325 xx 10^(3)(2-0.01)`
`=-201.6` kJ
