1 Vapor pressure equation for liquid zinc is given by the following expression 6676 log p mmHg 1 7210gT 12 448 T The triple point temperature for zinc is 419 C and the pressure at this temperature is 0 0082 atm The melting temperature of zinc is 420 C and enthalpy of melting of zinc is 1740 cal mole degree a A piece of zinc placed inside a ceramic crucible is heated in an evacuated chamber to elevated temperatures in order to generate a zinc vapor pressure of 0 2 atm inside the chamber To what temperature zinc should be heated to get this atmosphere b What would be the vapor pressure of zinc inside the chamber when zinc was
