Practice Problem BUILD AH; of hydrogen chloride [HCl(g)] is –92.3 kJ/mol. Given the following data, determine the identity of the two missing products and calculate AHan for Equation 3. [Hint: Start by writing the chemical equation that corresponds to AH? for HCI(g).] N2(8) + 4H2(8) + Cl½(g) - 2NH,Cl(s) AHan = -630.78 kJ/mol (1) N2(g) + 3H2(g) 2NH3(g) ΔΗ -92.6 kJ/mol (2) NH,Cl(s) (3)

The following chart below is a plot of VLE data from the Dortmund data bank for a binary mixture of acetone (1) and isopropanol (2) at a constant temperature of 328.15 K. Values for the plot are also included in the table below. The saturated vapor curve is magenta, and the saturated liquid curve is cyan. Answer the following questions related to VLE.
