What is the Kb of benzene

Please define Kb. Do you mean the boiling point elevation constant?

no

Yes, when referring to Kb in the context of boiling point elevation, it stands for the boiling point elevation constant. The boiling point elevation constant, Kb, is a proportionality constant that relates the change in boiling point of a solvent to the concentration of a nonvolatile solute in the solvent.

To find the value of Kb for benzene, you would typically refer to a reference source like a chemistry textbook, handbook, or online database. These sources provide tables or lists of Kb values for different solvents, including benzene.

It's important to note that the boiling point elevation constant, Kb, is unique to each solvent and can vary depending on the specific conditions. Therefore, it is necessary to consult a reliable source to obtain the accurate Kb value for benzene.
