The equilibrium expression for the base dissociation constant ((K_b)) of the weak base C5H5N (pyridine) can be described by the reaction: C5H5NH(^+) + OH(^-) ⇌ C5H5N + H2O. To calculate (K_b), you can use the relationship (K_b = \frac{[C5H5N][H2O]}{[C5H5NH^+][OH^-]}). However, for a specific numerical value of (K_b), you would need experimental data or literature values for the concentrations of the species at equilibrium.

The base dissociation constant (Kb) for methylamine (CH3NH2) can be determined from its equilibrium reaction with water, where CH3NH2 accepts a proton to form CH3NH3+ and hydroxide ions (OH-). The Kb value indicates the strength of CH3NH2 as a base, reflecting its ability to generate OH- in solution. For methylamine, Kb is approximately 4.2 × 10^-4, highlighting its moderate basicity. This value can be used in calculations involving the concentration of hydroxide ions produced in a solution of methylamine.
The base dissociation constant (Kb) for methylamine (CH3NH2) in water is a measure of its ability to accept a proton (H+) from water, forming CH3NH3+ and hydroxide ions (OH-). The equilibrium expression for this reaction is given by Kb = [CH3NH3+][OH-] / [CH3NH2]. For methylamine, Kb is approximately 4.2 × 10^-4 at 25°C, indicating its relatively weak basicity compared to stronger bases.
The equilibrium constant (Kb) for the reaction of methylamine (CH3NH2) with water to form the methylammonium ion (CH3NH3+) and hydroxide ion (OH-) is a measure of the base strength of methylamine in aqueous solution.
