- For liquid zinc, the measured vapour pressures at 627 °C and 977 °C are given as 9.5 x 10-3 atm and 0.116 atm,respectively. Melting temperature of zinc is 419 °C and enthalpy of melting for zinc is 7280 J/mol. Using this informationderive the equation used to determine the equilibrium vapour pressure with solid zinc.In the study of the vapour pressure of chloroform is determined. Chloroform is placed in a container and allowed to reach a temperature op 28C. A vacuum is then created at which point the chloroform start to boil. The pressure and temperature are recorded. Subsequently the vacuum is gradually reduced by allowing a small amount of air into the vessel, thereby increasing the pressure in the vessel. At each of these higher pressures, the solution is heated and till it boils again and the temperature point and pressure is recorded at which the solution boils. This is repeated until the vessel reaches room pressure. What is the dependent and independent variable?For liquid zinc, the measured vapour pressures at 627 °C and 977 °C are given as 9.5 x 10-3 atm and 0.116 atm,respectively. Using the derived equation to calculate the boiling temperature (TB,Zn) and enthalpy of boiling for zinc (∆HB,Zn).
