Unformatted text preview: a and b parameters have pretty clear cut physical meaning. What are the physical meanings of a and b ? Prove whether f is always <, =, or > P when the gas molecules have zero interactive forces between them (i.e. not sticky or repulsive), but they do have significant size. Does the answer make physical sense? That is, in the absence of interactive forces, does the difference between f and P increase, decrease, stay the same, etc as b increases, and does this trend make physical sense? Practical 4. Water vapor is in equilibrium with liquid water. The temperature is 350 o C. What are the numerical values of the fugacities of the liquid and vapor that can be determined when (a) The Law of Corresponding States is used? (b) Information from the Steam Tables is used?...
