Vapor pressure

The vapor pressure of ethanol is 400 mmHg at 63.5 C.  Its molar enthalpy of vaporization is 39.3 K Joule/mol.  What is the vapor pressure of ethanol, in mmHg, at 34.9 C?  Show work.

For iodine, the molar enthalpy of sublimation is 62.3 k Joule/mol. The molar enthalpy of fusion is 15.3 k/Joule/mol.  Calculate the molar enthalpy of vaporization of liquid ioline.  Show work. Thanks for your help.
