Homework Help: Clausius Clapeyron equation

  1. Feb 3, 2008 #1
    Hi I am stuck on this question. I am given the slope of a ln vapor pressure vs. invert kelvin temp equals -8.000 x 10^3 K. I am supposed to find delta H (or the heat of vaporization). If anyone could help that would be great!

    Can you write out the Clausius-Clapeyron equation for us?

    ln P= [-delta H (heat of vaporizaiton)/R] * [1/T] + C

    R=8.3145 j/mol
