26. Consider the reaction: 2HBr(g) = H2(g) + Br2(g) Keq = 49.0 If 1.20 M H2, 1.20 M Br2 and 1.00 M HBr are placed into a container at 44° C, which of the following is true as equilibrium is approached? A. [Br2] decreases significantly. B. [HBr] decreases significantly. C. [H2] decreases significantly. D. [H2) remains the same. 27. Which Keq is most likely to favour the formation of reactants? A. B. c. D. Keq = 1.65 x 104 Keq = 5.69 x 10-11 Keq = 3.95 x 10-11 Keq = 7.67 x 104 28. Which Keq is most likely to favour the formation of products? A. B. c. D. Keq = 1.65 x 10-4 Keq = 5.69 x 10-11 Keq = 3.95 x 10-11 Keq = 7.67 x 10-4 29. Consider the following equilibrium system: 2NO(g) + Cl2(g) = 2NOCI(g) + 25 kJ In which direction will the equilibrium shift and what happens to the value of keq when the temperature of the system is increased?
