Question

1. Some vapor pressure data for ethanol/water solutions at 298 K are given in the table below. Plot these data and use them to numerically determine the Henry's Law constant for ethanol in water and for water in ethanol (different extremes). x (ethanol) $P_{ethanol}$ (torr) $P_{water}$ (torr) 0.00 0.00 23.78 0.02 4.28 23.31 0.05 9.96 22.07 0.08 14.84 22.07 0.10 17.65 21.70 0.20 27.02 20.25 0.50 36.86 17.29 0.80 48.24 9.89 0.90 53.45 5.38 0.93 55.14 3.83 0.96 56.87 2.23 0.98 58.02 1.13 1.00 59.20 0.00 (a) Henry's Law constant for $CH_3CH_2OH$ in $H_2O$ (for pressure in torr) (b) Henry's Law constant for $H_2O$ in $CH_3CH_2OH$ (for pressure in torr)
