Starting with the mole fraction of dissolved chlorine in the aqueous phase calculated in Problem 12.9 (x_a ), use Raoult’s law to estimate the partial pressure of chlorine in the gas phase. What percentage error results from this estimation, presuming that the value of p_Cl2 from Problem 12.9 is correct. Why is such a large error not surprising?

This problem deal with the chlorine absorber, depicted in the following flowchart.
