The separation achieved in a distillation column depends primarily on:

a$)$ Reflux ratio

b$)$ Feed flow rate

c$)$ Column height

d$)$ Column diameter

The reflux ratio that ensures the maximum separation between the distillate and bottoms product is known as:

a$)$ Total reflux

b$)$ Minimum reflux

c$)$ Optimum reflux

d$)$ Infinite reflux

The ratio of the vapor flow rate to the liquid flow rate in a distillation column is known as:

a$)$ Reflux ratio

b$)$ Rectification factor

c$)$ Stripping factor

d$)$ Murphree efficiency

In a distillation column, the stage with the highest concentration of the more volatile component is typically:

a$)$ The top stage

b$)$ The bottom stage

c$)$ The feed stage

d$)$ The stage with maximum reflux
