1A. Arrange the following in order of increasing vapor pressure: CH3CH₂CH₂OH, CH4, H₂O, liquid helium, (CH3)2CHOH, CHCl3 18. 15.0 g of a gas starting at 0.0 °C is heated to a solid at 85.0 °C. The following data is provided: The substance undergoes phase changes at 85.0 °C and 10.0 °C. The heat of condensation is 3.00 kJ/g and the heat of crystallization is 1.00 kJ/g. The heat capacity of the gas is 0.100 kJ/g °C. (8 points) The heat capacity of the liquid is 0.0500 kJ/g *C. The heat capacity of the solid is 0.0300 kJ/g °C. Draw a labeled heating curve (using the table below) showing the phase transitions that occur during this process AND calculate (Q. 1C show your calculations in the next page) the enthalpy for the entire process: (6 points for graph)
Question 1C: Calculations (12 points for calculations) 1D. (NPC 3 pts) A solution of SrCl3 is prepared by dissolving 0.124 g of the compound in water. The solution boils at 101.0 °C. Which statement is true? i) The solution is saturated ii) The vapor pressure of the solution is lower than that of the solvent iii) The solution is super saturated iv) The vapor pressure of the solution is higher than that of the solvent
