The normal boiling point of a liquid is 282.0 °C. What is the vapor pressure of this liquid at 161.0 °C in atm? (∆Hvap = 28.5 kJ/mol)

Silica, sio2, is formed on silicon as an electrically insulating layer for microelectronic devices. silica is formed when silicon is exposed to o2 gas at an elevated temperature. at 900˚c, it takes 90 minutes for the oxygen to diffuse from the surface to form a 0.06 micron (0.06 x 10-6 m) thick layer of sio2 on
