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?

Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 75.0 L tank with 6.1 mol of ammonia gas, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 3.7 mol. Calculate the concentration equilibrium constant for the decomposition of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits.

How did the change of stress (adding or removing reactants or products) cause a shift in the equilibrium system of the solutions (in which direction) use an example. Use trial one as an example
help please answer in text form with proper workings and explanation for each and every part and steps with concept and introduction no AI no copy paste remember answer must be in proper format with all working
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.
