Q2. What Is reflux ratio.
Ans. 
Reflux ratio is the ratio of the amount of liquid refluxed to the amount of liquid that is being distilled.
• It is an important parameter in distillation processes.

• It helps in determining the efficiency of the distillation column.

• A high reflux ratio results in a higher purity of the distillate.

• Reflux ratio can be adjusted to optimize the distillation process.

• It is calculated as the ratio of the reflux flow rate to the di
