The vapor pressure of ethanol is 400 mmHg at 63.5 C. Its molar enthalpy of vaporization is 39.3 K Joule/mol. What is the vapor pressure of ethanol, in mmHg, at 34.9 C? Show work.
The Clausius - Clapeyron equation predicts the temperature dependence of vapor pressures of pure liquids or solids:
ln (P/P°) =
where P is the vapor pressure, P° is a vapor pressure at a known temperature T°, H ...
The expert examines vapor pressure of ethanol.
Mean difference and P value questions
See attached for data.
2. The table below provides data on the theoretical calculated and experimental test values of the vapor pressures for dibenzothiophene, a heterocyclloaromatic compound similar to those found in coal tar. If the theoretical model for vapor pressure is a good model of reality, the true mean difference between the experimental and calculated values of vapor pressure for a given temperature will be 0. (a) State the correct hypothesis that the mean difference equals zero (0) and conduct the hypothesis test at α = 0.05. (b) Interpret the pvalue for the test.View Full Posting Details
