Concept explainers
Interpretation:
The given table, which involves Raoult’s law, is to be completed.
Concept introduction:
If the
Positive deviation from Raoult’s law is shown when the vapor pressure of the components in the solution is greater than what it should be according to Raoult’s Law.
For positive deviation,
For positive deviation, the forces of attraction between the solute-solvent forces are weaker than theforces between solute-solute and solvent-solvent.
For negative deviation, the forces of attraction between thesolute-solvent arestronger than the forces of attraction between the solute-solute and the solvent-solvent interactions.
Negative deviation from Raoult’s law is shown when the vapor pressure of the componentsin the solution is less than what it should be with respect to Raoult’s Law
For negative deviation,
When the intermolecular forces of attraction between the components of a solution are nearly equal, it is said to be an ideal solution.
