A solution of ethanol (eth) and chloroform (chl) at 45°C with xeth = 0.9900 has a vapor pressure of 177.95 torr. At this high dilution of chloroform, the solution can be assumed to be essentially ideally dilute. The vapor pressure of pure ethanol at 45°C is 172.76 torr. (a) Find the partial pressures of the gases in equilibrium with the solution. (b) Find the mole fractions in the vapor phase. (c) Find the Henry's law constant for chloroform in ethanol at 45°C. (d) Predict the vapor pressure and vapor-phase mole fractions at 45 °C for a chloroform-ethanol solution with xeth = 0.9800. Compare with the experimental values  P = 183.38 torr and   = 0.9242.
