The table below presents equilibrium distribution data for four gaseous solutes dissolved in water, using air as the carrier gas:

a. Using a spreadsheet to perform the calculations, prepare a graph of the equilibrium distribution data for each solute as partial pressure in the gas vs. molar concentration dissolved in the liquid (p_A €“ c_AL), and also in mole fraction coordinates (y_A €“ x_A) at 1.0 atm total system pressure. Which solute is the most soluble in water? Which solute dissolved in water can be stripped into air the easiest? 

b. For each solute at the appropriate concentration range, estimate the Henry€™s law constant (H) based on the definition p_A = H c^*_AL, and the distribution coefficient m based on the definition y_A, = mx^*_A at 1.0 atm total system pressure.
