a.) Use the equipartition theorem to estimate C_v (in terms of nR/2) of water vapor at room temperature. Compare this to the literature value: 25.3 J/(mol K). Explain your answer in terms of the relative contributions from translation, rotation, and vibration considering the following spectroscopic constants: v_1 = 3650 cm^-1 v_2 =3760 cm^-1 v_3 = 1600 cm^-1 B_rot(ave) = 16 cm^-1 b.) Calculate the value of C_v using the full statistical theory at 3000 K.

700 grams of an ammonia-water liquid mixture containing 50 wt% ammonia is placed in a close container and heated to 100 °F. A liquid-vapor equilibrium mixture forms at this temperature. Use the lever rule to find the weight fraction of ammonia in the liquid and vapor phases. Find the mass of ammonia and water in each phase.

Ethanol is often used as a fuel additive, but to function in
most engines, the ethanol must be very pure and contain little
water. It is difficult to distill ethanol and water above 90 mole %
ethanol because at this concentration the vapor and the liquid
phases of this mixture have the same composition. To get around
this effect, benzene is often added to the mixture. The
distillation column then separates the mixture into a very nearly
pure ethanol stream,...
