with detailed explaination The vapour pressure of a liquid in the temperature range 200K to 260 K was found to fit the expression In(p/Torr)- 18.361 - 3036.8/ (T/K ) . Calculate the enthalpy of vaporization of the liquid.
7. The vapour pressure of a liquid in the temperature range 200 K to 260 K was found to fit the expression ln(p/Torr) = 16.255 – 2501.8(T/K). What is the enthalpy of vaporization of the liquid?
4) The vapour pressure of a liquid Chem 311 - Fall 2019 vapour pressure of a liquid in a certain temperature range is given by the formula a - b/T, where a and b are constants. Find the enthalpy of vaporization of the liquid. (Hints: Clausius-Clapeyron equation S: Clausius-Clapeyron equation; p is the numerical value of the pressure, i.e.it is dimensionless.)
1. The normal boiling point of benzene (i.e., at 1 atm) is 80.09 °C. The molar enthalpy of vaporization is 30.72 kJ mol . Assuming that AvapHm and AvapSm stay constant at their values at 80.09°C, calculate the values of AvapGm at 75.0 °C, 80.09 °C and 85.0 °C. Given your calculated values, do you still expect benzene to spontaneously condense at 75.0 °C and to spontaneously evaporate at 85.0°C? -1 2. The vapor pressure of a liquid was measured...
