$5.$ Partial condensation is a process where:

$-$ A$)$ Only the more volatile components condense.

$-$ B$)$ All components condense equally.

$-$ C$)$ The vapor is partially condensed to enrich the vapor phase in more volatile components.

$-$ D$)$ The entire vapor stream is condensed.

$6.$ Steam distillation is particularly useful for:

$-$ B$)$ Compounds that decompose at their boiling points.

$-$ C$)$ Inorganic salts.

$-$ D$)$ All volatile compounds.

$7.$ The McCabe$$Thiele method is used to:

$-$ B$)$ Heat and mass balances together.

$-$ C$)$ Only the mass balance.

$-$ D$)$ The relative volatility as a variable.
