Question
1. What is the difference between the equilibrium position and the equilibrium constant of a reaction? Which changes as a result of a change in reactant concentration? 2. What i8s implied by the work "constant" in "equilibrium constant"? Give two reaction parameters that can be changed without changing the equilibrium constant 3. Scenes A, B and C depict this reaction at three temperatures NH.CKs)NHg) HCg) (a) Which best represents the reaction mixture at the highest temperature? Justify your answer b) Which best represents the reaction mixture at the lowest temperature? Justify your answer . Acetic acid is miscible in water. Would you expect carboxylic acids, general formula CHa(CH2) COOH to become more or less water soluble as n increases?Explanation / Answer
1) If a dynamic equilibrium is disturbed by changing conditions, the equilibrium position is moved to counteract the change.
The Balance Constant is the result of the product between the reactants and the substances generated by the reaction, products.
The first changes and moves to form more products to counteract.
2) In a reaction in equilibrium involving gases, its variables are partial pressures of the gases, the work is a function of the volume change of a gas.
Parameter 1: Addition of Catalyst.
Parameter 2: Concentration of substances.
3) The mixture with the highest temperature is b, since at higher temperatures, there is a greater equilibrium constant, and the equilibrium constant is directly proportional to the concentration of products, which in this case are gases.
The mixture with the lowest temperature is A, with the opposite explanation of the previous case, it is the least abundant in gases.
4) It is less soluble in water, because water is very polar substance, and carbon chains are apolar substances, and its apolarity grows as a function of the growth of the amount of carbons.
5) KNO3 is diluted in water in higher concentration, approximately 38 gr KNO3 / 100 gr H2O.
7) a) CH3CH2OCH3: it is the one with the least amount of carbon (less apolar) of the pair.
b) CH2Cl2: Approximately 13 g / L of water.
