The following reaction has an equilibrium constant of 25. The molecular-level diagram shows a mixture of reactants and products at a given time. . 03(g) + NO(g) = 02()+NO2(8) NO2 NO O2 03 This system: will proceed towards products will proceed towards reactants is at equilibrium
About 80% of the ammonia produced by industry goes into the production of fertilizers. Ammonia is produced in industry by the reaction of N, and H, in the following reversible reaction: N2(g) + 3 H2(g) = 2 NH3(g) exothermic (a) Choose the conditions of pressure and temperature that favor the formation of the most amounts of ammonia. Increased ressure and lower Onperatures will favor the formation of ammonia. (b) Which conditions of temperature will increase the rate of formation of ammonia? Highnperatures will increase the rate of formation of ammonia. (c) Use your answers to parts (a) and (b) to determine whether the reaction should be run at extremely high temperatures, extremely low temperatures, or an intermediate temperature. The reaction should be run at an intermediate temperature
The indicator phenolphthalein changes from colorless to pink between pH 8.2 and pH 10. If phenolphthalein is added to a solution, and the solution remains colorless, then Multiple Choice x the solution is acidic, and the pH must be at or below 70. the pH of the solution must be below 8.2, and the solution is basic the pH of the solution must be below 8.2, but the solution could be either acidic or basic the pH of the solution must be above 10, and the solution is basic,
