In this lab, you will determine the vapour pressure of ethanol (P) at various temperatures and use this data to find the enthalpy of vaporization (ΔvapH).
If a plot of ln P vs. 1/T gives a slope of -9782 K, what is the ΔvapH in kJ/mol? Do not worry about how realistic the value is. Assume R = 8.314 J mol-1 K-1.
