The flow rates within a distillation column are typically much larger than the flow rates in and out of the column. Use physical reasoning to explain why this would be. To aid in this explanation, consider a column that is operating at some steady state. You then make a change in operating conditions that reduces the ratio of flow rates in the column vs. those in/out of the column. What sort of changes in operating conditions could cause such an effect, and what would be the consequences for separation achieved? Justify your answers.
