In an aqueous solution of a weak acid, HA, the assumption is often made that [HA]equilibrium = [HA]initial. This approximation is reasonable if the initial concentration of the acid is sufficiently large compared to Ka- What multiple of Ka must the initial concentration of a weak acid exceed, for the initial concentration and the equilibrium concentration to be within 5.20 percent of each other?

Le Châtelier Principle Learning Goal: To use the equilibrium constant and Le Châtelier's principle to determine how a reaction will respond to external factors. A reaction is at equilibrium when the concentrations of the reactants and products no longer change over time. This does not mean the reaction is over, rather, two competing reactions continue to occur simultaneously at equal rates. The two competing reactions are the forward reaction (reactants → products) and the reverse reaction (products → reactants). If a reaction at equilibrium is subjected to a stress, the concentrations of reactants and products adjust to reestablish equilibrium. This is called Le Châtelier's principle. A stress might be a change in the concentration of reactants or products, a change in the volume of the reaction container, a change in temperature, or the addition of a catalyst. 0 O ▾ Part A Given the concentrations, calculate the equilibrium constant for this reaction: 2SO2(g) +O2(g) = 2SO3(g) At…

Which of the following are not at equilibrium? Group of answer choices the concentrations of the reactants and the products do not change the rate of the reverse reaction does not change the rate of the forward reaction is twice as fast as the rate of the reverse reaction all of the above
According to Le Chatelier's principle, changes in concentration will induce stress on a system at equilibrium. How will the reaction shift to relieve stress induced by increases and decreases in concentration. Select all that apply. Select 2 correct answer(s) Decreasing the concentration of one substance causes the reaction to shift away from the side containing the substance that was removed. Increasing the concentration of one substance causes the reaction to shift towards the side containing the substance that was added. Decreasing the concentration of one substance causes the reaction to shift towards the side containing the substance that was removed. | Increasing the concentration of one substance causes the reaction to shift away from the side containing the substance that was added.
adding some CO(g) increasing the volume of the container removing some H₂O(g) Shifts in the direction of the products Shifts in the direction of the reactants chill the reaction removing H₂(g) as it forms Equilibrium does not change

MULTIPLE CHOICE Question 11 What does Le Châtelier's principle state? A Equilibrium cannot be re-established once it is disturbed. B A system at equilibrium will remain at equilibrium forever. A system will react to re-establish equilibrium if it is disturbed. A reaction will proceed to completion if equilibrium is disturbed.
