Calculate work done by 1 mole of Ideal gas expand isothermally and irreversibly from pressure of 5 atm to 2 atm against a constant external pressure of 1 atm at 300 K temperature.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(–0.7478 kJ )
= – 
W irr = –P ext [V 2 – V 1 ] = –P ext 
= –P ext × nRT 
= –1 × 1 × .082 × 300 
= –1 × .082 × 300 × 
= –7.38 L.atm = –747.8 J
W irr = –0.7478 KJ
