Vapor pressureLead bromideKnudsen effusion methodVapor speciesThe vapor pressure of PbBr2 solid was measured by the Knudsen effusion method assuming that the vapor species consisted only of monomers. The vapor pressure of PbBr2 fitted the following linear equation over the temperature range 532.3-633.9...
Arrange these compounds by their expected vapor pressure: H2O, NCl3, Br2. Which compound has the higher vapor pressure at a given temperature: CH4 or CH3Cl? Explain. What would the vapor pressure of molecules with no intermolecular force at all?
