Unformatted text preview: i and b i are constants. Because the equation has the form of Eq. (11.11), it might be that = a i + b i x i . Show whether this is true. 4) A vessel, divided into two parts by a partition, contains 4 mol of nitrogen gas at 75 o C and 30 bar on one side and 2.5 mol of argon gas at 130 o C and 20 bar on the other. If the partition is removed and the gases mix adiabatically and completely, what is the change in entropy? Assume nitrogen to be an ideal gas with C V = (5/2) R and argon to be an ideal gas with C V = (3/2) R. 5) Estimate the fugacity of isobutylene as a gas: a. At 280 o C and 20 bar b. At 280 o C and 100 bar...
