1. For the equilibrium system: 2 0, (9) 3 O, (9) AHO -285 kJ Predict the change in equilibrium sl: a. b c. d. and. the temperature is increased to constant volume. the volume is increased at constant temperature. 02 (g) is added at constant temperature and volume Os (g) is removed at constant temperature and volume the pressure is increased by adding an inert gas. 2. Consider the balance: CO, (9) + Hz (9) Predict the change in equilibrium if: Co (9) + Hzo (g) AH> 0 to. b the temperature is lowered to constant volume. the volume is decreased, at constant temperature. CO2 (g) is removed at constant temperature and volume. H2 (g) is added at constant temperature and volume. the pressure is increased by adding an inert gas. 3. The reaction A (9) + B (g) C (9) It is endothermic as it is written. When equilibrium is established, how the concentration of C (g) changes when: b. decreases the temperature MBOI BOUR Be OMOOL increase the pressure add A (g) a catalytic agent is added B (g) is removed Rou. B represents an acid-base indicator and behaves like a base. Your balance of dissociation in an aqueous solution can be written as: B (ac) + HOO BH (aq) + OH (aq) If B (ac) is yellow, BH is red. Using Le Chtelier's principle, predict the color of the indicator by adding a few drops of it to an aqueous solution of HCl and to an aqueous solution of NaOH. Write the corresponding chemical reactions
