and the references it needs H-13. Equation 16.5 gives P for the van der Waals equation as a function of V and T. Show that P expressed as a function of V, T, and n is nRT n2a Now evaluate (aP/aV), from Equation 16.5 and (aP/aV), from Equation 1 above and show that (see Problem H-12) a P H-12. Prove that and that a P T,n where Y = Y(P, T, n) is an extensive variable. We were unable to...
14-5. Using Eqs. (14-14) and (14-17), calculate the van der Waals constants a and b for nitrogen. For u(r), assume a Lennard-Jones 6-12 potential with ε and σ given in Table 12-3. Compare these calculated values to the experimentally determined values, a 1.39 x 106 cm atm/mole and b-39.1 cm/mole. Such poor agreement is quite typical, simply indi- cating the inadequacy of the van der Waals equation. 14-2 THE VAN DER WAALS EQUATION We start with Eq. (14-3), and take...
Hello, these are part of one question, please show work. Data Sheet Chemical Reactions 2. Obtain and clean with sandpaper to expose the surface: 3 pieces of zine, 2 pieces of copper and 1 piece of lead. Place 6 test tubes in a rack and label each appropriately. Observe the contents of each of the test tubes for evidence of a reaction. Record your observations in the tables below TABLE 55 Observations Tube I: Copper strip and approximately 1 mL...
