Question

Be sure to answer all parts. The molecular scenes above depict the aqueous reaction where D is red and E is blue, and each sphere represents 0.0100 mol. The volume in scene A is 1.00 L, and in scenes B and C, it is 0.500 L (a) If the reaction in scene A is at equilibrium, calculate Ke (b) Are the reactions in scenes B and C at equilibrium? Check all that apply. B is at equilibrium B is not at equilibrium, and the reaction will proceed to the right. B is not at equilibrium, and the reaction will proceed to the left C is at equilibrium. C is not at equilibrium, and the reaction will proceed to the right. C is not at equilibrium, and the reaction will proceed to the left.

Explanation / Answer

2D <====> E

a) Kc = [E]/[D]^2

   Kc = 0.03/(0.03)^2 = 33.33

b)

Qc of B = 0.03/(0.03)^2 = 33.33

Qc = Kc

B is at equilibrium

Qc of C = 0.01*6/(0.03)^2 = 66.67

Qc > Kc. so that, equilibrium will proceed to the left.

C is not at equilibrium, and the reaction will proceed to left.
