Vapour pressure of a liquid in the temperature range of 200Kto 260K is given by this expression
ln (p/Torr) = 16.255 - 2501.8(T/K)
Calculate the enthaly of vaporization of hte liquid
since this is the liquid vapour boundary
[tex] p = p^* e^-\chi [/tex]
and [tex] \chi = \frac{\Delta H}{R} (1/T - 1/T^*) [/tex]
so then the ratio of Ln p to ln p* would yield the expression for chi which i cna then solve for delta H but it doesn't yield that same answer
what am i doing wrog here can you push (or shove) me iin the right direction
i have an exam today thus i need to answer this once and for all
thank you for help!
