Unformatted text preview: Each side has a volume of 300 cm 3 . The pressure in the left side is 37.5 atm and the pressure in the right part is 84.5 atm. The left side is filled with 0.99 moles of ethane and 0.01 moles of helium; the right side is filled with 0.99 moles of nitrogen and 0.01 moles of helium. After equilibrium is attained, what are the mole fractions of helium in each part of the chamber? Assume that the virial equation truncated after the second term is applicable. Let 1 stand for helium, 2 for ethane and 3 for nitrogen. At 40 C the following second virial coefficients are reported (cm 3 /mole): B 11 = 17.17 B 12 = 24.51 B 22 = -169.23 B 13 = 21.97 B 33 = -1.55 B 23 = -44.39...
