$5$ Taking into account Table Q$5$ below for Henry constants for absorption with water.

$($a$)$ Which is the most volatile compound? Which is the most soluble? Justify your

choices.

$($b$)$ Consider $CO$ on water for its absorption at $40C$ and $1520mmHg.$ The height of

the gas phase transfer unit is $1\mathrm{.}37m$ and the height of the liquid phase transfer unit

is $1\mathrm{.}41m.$ The ratio for the gas flow rate divided by the liquid flow rate is $0\mathrm{.}833$ and

the number of transfer units is $3\mathrm{.}34$ times the slope of the operating line. Calculate

the height of the column. Is this a situation with gas film, liquid film or both films

control?
