Mass Transfer
A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state,

The top and bottom compositions are unchanged with and without total reflux
Reboiler load and condenser load are minimum
The top and bottom compositions correspond to the maximum enrichment available
Composition of vapors and that of liquid do not vary throughout the column

Mass Transfer
If a two phase system is in physical equilibrium; then it means that, the

Escaping tendency of each component from the liquid phase to the vapor phase is exactly equal to that from vapor phase to liquid phase
Total pressure throughout the liquid phase is equal to that throughout the vapor phase
Temperature of the liquid phase is equal to that of the vapor phase
All of these
