Partial pressure of a component
Webcomponent to its vapor pressure as a pure li quid is approximately equal to the mole fraction XA in the solution i.e., A A A X p p = ∗ or pA = XA p*A. (1.60) The Eq. (1.60) is known as the Raoult’s law. Linear dependence of the partial vapor pressures pA and pB are shown by the dashed lines in Fig. 6. WebWhat is the partial pressure of the dry gas? chemistry Consider a sample of a hydrocarbon at 0.959 atm and 298 K. Upon combusting the entire sample in oxygen, you collect a mixture of gaseous carbon dioxide and water vapor at 1.51 atm and 375 K.
