The Clausius-Clapyeron equation ln(p2/p1) = -ΔH_{vap}/R (1/t2 - 1/t1) is derived assuming that ΔH_{vap}is independent of temperature.

Find ΔH_{vap}as a function of temperature for ethanol at constant external pressure.

2. Relevant equations

these are not relevant equations but the equations that i tried solving using-

dU = TdS − pdV

3. The attempt at a solution

i tried starting with the equation for dh and integrating it. i also tried to derive using the clapyeron equation dp=(ΔH/tΔv) dt but i keep getting stuck. the other half of the question asks to derive the clausius clapyeron using the ΔH of this question so I am skeptic about the way I have approached this question.
