Examine the magnitude of your calculated equilibrium constant, Keq. Does the equilibrium favor reactants or products? Explain your answer. Saved Normal BIUXX Tx 2. The reaction was begun with glacial (anhydrous) acetic acid and anhydrous ethyl alcohol (ethanol). The reaction would also work if you had started with a lower grade of acetic acid (80% m/m acetic acid in water) and 95% m/m ethanol, which are commonly available in chemistry stockrooms. What changes would you need to make in your calculation for Keq if the reaction had been carried out with a lower grade of acetic acid and 95% ethanol, and therefore has some amount of water in the initial set-up of the reaction? (1 pts) A. Water must be eliminated from the equation for Keq because the reaction is now happening in a dilute aqueous solution B. The equilibrium concentration of water increases; you must add the initial concentration of water to the concentration of water produced by the reaction. C. No change is needed because the small amount of water in these reagents will have no effect on the Choose... reaction. D. The term (H20), must be moved to the denominator because water is available at the start of the reaction and is now a reactant E. The equilibrium concentration of water decreases; you must subtract the initial concentration of water from the concentration of water produced by the reaction. E 3. Students wanted to test ways of improving the amount of ethyl acetate produced. One student added 20 ml of water to the cauilibrium mixture at A D Saved B 3. Students wanted to test ways of improving the amount of ethyl acetate produced. One student added 30 mL of De water to the equilibrium mixture at the end of the activity. How will the addition of water effect the concentration of ethyl acetate? (1pts) A. The reaction is at equilibrium so there will be no effect on the concentration of ethyl acetate. B. According to the Le Chtelier principle, the addition of water shifts the reaction to the left and decreases the concentration of ethyl acetate. C. According to the Le Chtelier principle, the addition of water shifts the reaction to the right and decreases the concentration of ethyl A acetate. D. According to the Le Chatelier Choose... principle, the addition of water shifts the reaction to the left and increases VA the concentration of ethyl acetate, E. According to the Le Chtelier principle, the addition of water shifts the reaction to the right and increases the concentration of ethyl acetate. D 4. Another student added a drying agent (anhydrous absorbs water removing it mixture) to the equilibrium E activity. How will the addition of a drying agent effect the concentrator ethyl acetate?
