Question
In the development of the Claudius Chaperon equation, what was the principal assumption? Consider the vaporization process you will be modeling in this lab: BR at B(t) Delta H & Delta S. Predict whether the process will be endothermic or exothermic, predict whether the system entropy would increase or decrease. Enthalpy of vaporization (Delta H): expected sign Entropy of vaporization (Delta S): expected If the assumption in question MI is correct, and the signs for Delta H & Delta S follow your prediction in question U2, what would you expect the experimental data to look like if you plotted In (vapor pressure of (absolute temperature as predicted by the linear zed form of the Claudius- Chaperon equation (Eq 6)? A glass Erlenmeyer flask is introducing liquid into the flask there is some air already present. Imagine you stopper the air-filled flask, then heated the gaseous contents by warming the water surmounting the flask. Premiership you think would happen to the air pressure in the flask as the temperature rises. The ideal gas law is shown below, with subscript A" for air. In the scenario described above, circle the variables in the ideal gas law that would be constant. In the actual lab, you will introduce liquid B into the stopper Erlenmeyer flask, and mixture of air and vaporized liquid will be present. Which do you predict will change more with vapor pressure of B (Pa)? What is your rationale?Explanation / Answer
Vapor Pressure of B will NOT change, since this is dependent of Temperature
therefore
the Partial Pressure of air, will change FASTER
because, as B vaporises/condenses, the amount of moles of vapor incrase/decrease
therefore, the total Pressure changes, meaning that the partial pressure of air is affected directly
