Constant molal overflow is a term used in binary distillation. When a 2 component mixture is being separated in a distillation column,the assumption of constant molal overflow means assuming that both components have the same enthalpy.
It assumes that one mole of component 1 when it condenses will vapourise 1 mole of component 2,also assumes no heat loss from the column.
Can be wildly innacurate,particularly with separating organic solvents,and water. Water has a uniquely high enthalpy,often 5-6 times higer than the organic solvents.
What else can I help you with?
Does molal elevation constant depend on nature of solvent?
This is a colligative property which does not depend on the nature of solute is the molal boiling point elevation constant or ebullioscopic constant of the solvent.
What is molal depression constant?
Molal depression constant (Kf) is a colligative property constant that relates the lowering of the freezing point of a solvent to the molality of a solute in the solution. It is specific to each solvent and typically expressed in units of °C kg/mol.
What is the freezing point depression constant for water?
The freezing point depression constant for water is 1.86 degrees Celsius per molal.
How much would the freezing point decrease if a 3.23 molal solution were achieved?
The freezing point depression of a solution is given by the equation ΔTf = Kf * m, where ΔTf is the freezing point depression, Kf is the cryoscopic constant, and m is the molality of the solution. With the molality (m) of 3.23 molal and the cryoscopic constant for water (Kf) being approximately 1.86 ºC kg/mol, you can calculate the freezing point depression.
The molal freezing point constant kf is a property of the solvent not the solute What does this say about the fact that freezing point depends on the amount of solute rather than solute's nature?

What is the molar freezing point constant?
The molar freezing point constant (Kf) is a physical constant that represents the amount by which the freezing point of a solvent is lowered for each mole of solute dissolved in it. It is specific to each solvent and is used in calculating the freezing point depression in colligative properties.
Is the molal and molar solution of NaCl the same?
yes
What information is most useful to determine the solution that has a lower freezing point?
To determine which solution has a lower freezing point, you need the concentrations of solute in each solution and their respective properties (molal freezing point depression constants). The solution with the higher concentration of solute and lower molal freezing point depression constant will have the lower freezing point.
How much is a molal?
A molal is a unit of concentration that represents the number of moles of solute per kilogram of solvent. It is calculated by dividing the number of moles of solute by the mass of the solvent in kilograms.
Why does the overflow reservoir overflow?
because the entire point of the overflow resovoir is to overflow, and release uneeded water
Which two Latin words mean overflow?
There are a number of (single) words available, inrigo as in to overflow or irrigate, abundo as in to be abundant and overflow, superfundo as in to flood or overflow, restagno as in to be swamped or overflow, exundo as in to flow out or overflow, adfluentia as in to overflow with abundance
