The vapor pressure of methanol (l) is given by In P 23.593 - 3.6791 x 103/(T 31.317) where pressure is used in Pa and temperature in K. (a) Calculate the standard boiling temperature (at 1 atm). (b) Calculate AHyap at 298 K and at the standard boiling temperature.
The vapor pressure of ethanol is 1.00 x 102 mmHg at 34.90oC. What is its vapor pressure at 51.73 oC? (ΔHvap for ethanol is 39.3 Kj/mol.) Given the vapor pressure at one temperature, P1, we can calculate the vapor pressure at a second temperature, P2. In (P1/P2) = ΔHvap/R (1/T2 - 1/T1) Where, ΔHvap for ethanol must have the units of J/mol. R = 8.314 J/K.mol .. The temperatures must be in Kelvins. Solve for P2, What is the vapor...
The vapor pressure of ethanol is 115 torr at 34.9 oC and ΔHvap of ethanol is 38.6 kJ/mol, use this information and the Clausius-Clapeyron equation (shown below) to calculate the temperature in oC at which the vapor pressure is 760 torr (remember to convert temperatures to K in the equation (K = oC + 273). R = 8.314 J/mol·K. ( Please show each step, step BY step) I am having difficult with finding T2
The vapor pressure if ethanol (C2H5OH) is 672 torr at 75°C. The vapor pressure of water is 289 torr at the same temperature. Calculate the mole fraction of ethonal and water in a solution that is 12% ethanol by volume. Can any one help me step-by-step with this?
The vapor pressure of ethanol at 34.7 degrees Celsius is 100mmHg, and Hvap= 38.6 kJ/mol. What is the normal boiling point temperature of ethanol.
The vapor pressure for pure ethanol and pure propane is measured as a function of temperature. In each case, a graph of the ln of the vapor pressure versus 1/T is found to be a straight line. The slope of the line for ethanol is − 4643 K, and the slope of the line for propane is − 1888 K. Determine ΔHvap for propane.
