Answer to Question #278010 in General Chemistry for umut

Question

1 mole of O2 gas at 1 bar and 0 C was compressed from 22.71 L to 2.25 L under isothermal conditions

a) Calculate ΔG for this compression process by using Van der Waals equation

b)Calculate ΔGR

Answer 1

$G= nRT ln(V1/V2)$

R= 8.314

n = 1

T= 273.15K

V1= 22.7

V2= 2.25

G= 1×8.314×273.15 ln(22.7/2.25)

=5245.94J/mol
