Two gases, a and b, are at equilibrium in a sealed cylinder. individually, gas a is colorless, while gas b is dark colored. the reaction might be written as: a(g) equilibrium reaction arrow 2 b(g). (a) the cylinder should appear (color or colorless) (b) when the system is cooled, the cylinder's appearance becomes very light colored. therefore, the reaction must be (endothermic or exothermic) suppose the reaction equation were written as follows: 2 b(g) equilibrium reaction arrow a(g) (c) which of these statements would then be true? (select all that apply.) a the value of k would not change. b the δh value would have the same magnitude value but opposite sign. c the k expression would be inverted. d the color of the cylinder would be darker.
