Which statements are true in the following choice? Select all that apply.

Question 16 options:

Consider the reaction mixture pictures in the graphic labeled "Chemical Equilbrum Graphics" showing the following reaction of ethylene with halogens. Each molecule represents one mole of substance, and the volume of each reaction container is 1 L.

C2H4 + X2 <-> C2H4X2

X2 = Cl2 (a), Br2 (b), I2 (c)

The picture that shows the reaction mixture with the second highest equilibrium constant is picture b because it shows less amounts of products than picture a and more than picture c

The picture that shows the reaction mixture with the second highest equilibrium constant is picture c because it shows less amounts of products than picture a and more than picture b

The graphic of the correct answer to the previous question shows that the expression and value of K, the equilibrium constant, is [C2H4X2] / ([C2H4] x [X2]) = 6 / (4 x 4) = 3.75E-1.

The graphic of the correct answer to the previous question shows that the expression and value of K, the equilibrium constant, is [C2H4X2] / ([C2H4] x [X2]) = (4 x 4) / 6 = 2.67.

Adding extra amounts of Br2 to the reaction mixture results in shifting the equilibrium toward formation of C2H4 and Br2 and consumption of more C2H4Br2
