STEP 4 Assume that the initial concentration of weak acid is approximately equal to the equilibrium concentration. Web2 jan. 2024 · This example problem demonstrates how to find the equilibrium constant of a reaction from equilibrium concentrations of reactants and products. Problem: For the reaction H 2 (g) + I 2 (g) ↔ 2 HI(g) At equilibrium, the concentrations are found to be [H 2 ] = 0.106 M [I 2 ] = 0.035 M [HI] = 1.29 M What is the equilibrium constant of this reaction?
WebA weak base is any base that reacts with water (accepts H + ions) to a very small extent, usually less than 5 - 10%. An aqueous solution of a weak base in a state of equilibrium would consist mainly of the unionized form of the base, and only a small amount of hydroxide ions and of the cation (conjugate acid) of the weak base.
