The following table gives the mole fraction of methylbenzene (A) in liquid and gaseous mixtures with butanone at equilibrium at 303.15  K and the total pressure p. Take the vapour to be perfect and calculate the partial pressures of the two components. Plot them against their respective mole fractions in the liquid mixture and find the Henry's law constants for the two components. xA 0 0.0898 0.2476 0.3577 0.5194 0.6036 yA 0 0.0410 0.1154 0.1762
