Solvent Density (g cm-3) Boiling point (°C) K b (°C⋅kg/mol) Freezing point (°C) K f (°C⋅kg/mol) Data source; Aniline: 184.3 3.69 –5.96 –5.87 K b & K f [1]: Lauric acid: 298.9 44 –3.9 Acetic acid

K f is the depression in freezing point produced by 1 molal solution of a nonvolatile solute while Kb is the elevation in boiling point produced by 1 molal solution of a nonvolatile solute.

Sep 7, 2022 · Answer: The Kf and Kb have the same SI unit and the differences are Kb is elevation boiling point constant while Kf is depression freezing point constant. Explanation: Kb: …

Mar 6, 2024 · The value of the equilibrium constant K can be calculated by the ratio of the forward reaction's equilibrium constant (Kf) to the backward reaction's equilibrium constant (Kb). …

Sep 4, 2022 · Kf is a constant for a given solvent. Kf is called the molal freezing point depression constant and represents how many degrees the freezing point of the solvent will change when …

Apr 5, 2021 · Difference between Kf and Kb: Kf is the depression in freezing point produced by 1 molal solution of a nonvolatile solute while Kb is the elevation in boiling point produced by 1 …

Mar 16, 2021 · The proportionality constant, Kf, is called the molal freezing-point depression constant. It is a constant that is equal to the change in the freezing point for a 1-molal solution …

Jan 4, 2021 · The value of Kf is greater than Kb because a larger Kf means products are favored at equilibrium, indicating a higher affinity between ligand and receptor.

With respect to the forward reaction, kf denotes the velocity constant. Now, the rate at which C and D react together ∝CD. As a result, the backward reaction rate is equal to kb [C] [D]. For …

Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is a family of transcription factor protein complexes that controls transcription of DNA, cytokine production and cell survival.
