5 mole of an ideal gas expand isothermal...

5 mole of an ideal gas expand isothermally and irreversibly from a pressure of 10 atm to 1 atm against a constant external pressure of 1 atm. `w_(irr)` at 300 K is :

A

`-15.921 kJ`

B

`-11.224 kJ`

C

`-110.83 kJ`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
`int dw=-intP_("ext").dV`
`therefore" "w_("irr")=-P_("ext")[(nRT)/(P_(2))-(nRT)/(P_(1))]`
`w_("irr")=-1xx(5xx8.314xx300)xx[1-(1)/(10)]`
`w_("irr")=-11.224 " kJ"`
