Homework Help: P-Chem: Van der Waals Equation data

  1. Sep 11, 2012 #1
    1. The problem statement, all variables and given/known data

    Based on values for the Van der Waals equation tabulated in Table 1.6 in
    appendix A, determine an approximate molecular volume for CCl4 and CH4.

    Rationalize these values based on reasonable bond lengths and other
    parameters. The Lennard-Jones potential energy function is often used to
    model interactions between molecules.

    2. Relevant equations

    V(r) = 4ε [{σ/R}^12 - {σ/R}^6]

    For Cl, ε = 357/k, σ = 4.115 Angstrom
    For H, ε = 33.3/k, σ = 2.968 Angstrom

    3. The attempt at a solution

    No attempt has been made as of yet, except for logging on this site and requiring assistance!

    That doesn't count as an effort. Try harder.

    C'mon, I'm coming here for help, not to be told how to study. I learn when things are explained to me which, ironically, most of my professors fail to do. At least give me a step forward in the right direction so I can quickly solve the problem. I don't have time for a thorough comprehensive reading on the subject.
