Question
Two moles of an ideal gas compressed isothermally (100oC) and revversibly from a pres sure of 10atm to 25 atm, then the free energy cahnge is :
Options
A.+15.482 kJ
B.+10.462kJ
C.+5.684 kJ
D.+3.364 kJ
Solution
For isothermal reversible process,
Wrev = - 2.303 nRT log
= - 2.303 × 2 × 8.314 × 373 log
= + 5684.1 J = 5.64 kJ
Wrev = - 2.303 nRT log
= - 2.303 × 2 × 8.314 × 373 log
= + 5684.1 J = 5.64 kJ
