Antoine’s Equation and the Clausius-Clapeyron Equation

Dear Class,


When Antoine’s equation is combined with the Clausius-Clapeyron Equation DeltaH becomes:

DeltaH=BRT2/(C’+T) 2

There may have been a missing exponent when this equation was presented in class. Note that B, C’, and T have units of Kelvin. The US edition of SVA gives C in Celsius in Table B.2, therefore C’=C-273.15. International editions of SVA may already give C in Kelvin.
