Clausius-Clapeyron equatioin's constant for methanol

  1. Jul 4, 2005 #1
    Hi everyone!!
    I'm searching for the constants in Clausius-Clapeyron equation

    lnP=A-C/T

    I'ld like to know the value of A and C. (for Pressure unity is hPa and Temperature is K )

    Thanks

    They depend on the material under consideration, and on conditions like temperture and pressure. For water you could look at some steam tables. What the equation says is that log P and 1/T are linear as a 1st approximation. The equation can be used to interpolate a data set. Ie you know P(T) for water in 5 K increments from 273 to 373 and want to know P(300.62).
