a) For n-hexane the vaporization enthalpy and entropy are given (AHvap = 29.6 kJ mol‍ 1; ASvap = 86.5 J mol‍¹ K-1). Calculate the boiling point when ambient conditions are used. b) Compare AHvap and ASvap. Which of the two values is nearly unchanged for many "normal" substances? Is there a behaviour or rule? Which compounds have an abnormal behaviour and why?
Given the phase diagram for iodine (I2) below, predict what happens when an iodine sample is heated from 50°C to 250°C at a constant pressure of 1 atm. Note that the pressure and temperature values are just estimates.
Hello, can you please help me to solve this with using enthalpy and entropy
The normal boiling point of cyclohexane is 80.74 °C.At 20.00 °C, the vapour pressure of cyclohexane is 0.1026 atm.What is the vapour pressure of cyclohexane when the temperature is 33.00 °C? ----------------------------------------------------------------------------------- The vapour pressure at the normal boiling point is known, by definition, to be 1 atm.You therefore can write three different equations of the sort:lnPvap = [(−∆H)/(RT)] + Ci.e. for each of the three pairs of P and T.You can take the difference between the equations for the cases (Pb, Tb) and (P1, T1).This could be used to solve for [(−∆H)/(R)].Analogously you can take the difference between the equations for the cases (Pb, Tb) and(P2, T2).Since both differances must give rise to the same value for [(−∆H)/(R)], you can equate them to write an equation which allows you to calculate P2 in terms of Pb, Tb, P1, T1 and T2

Determine the entrophy change of (kJ/K) associated to the conversion of 10 kg of ice at -11 degrees celcius to steam at 121 degrees celcius
ANS B ONLY a. The molar volume of a certain solid is 142.0 cm3 mol−1 at 1.00 atm and 427.15 K, its melting temperature. The molar volume of the liquid at this temperature and pressure is 152.6 cm3 mol−1. At 1.2 MPa the melting temperature changes to 429.26 K. Calculate the enthalpy (KJ/mol) and entropy of fusion (J/mol-K) of the solid. b. Calculate the melting point of ice under a pressure of 10 MPa. Assume that the density of ice under these conditions is approximately 0.915 g cm−3 and that of liquid water is 0.998 g cm−3. From the result of the calculation, what happens when you increase the pressure on water, will it freeze or will the ice melt?
