Which of the following statements about chemical equilibrium are true?
Identify the reaction which does not show a homogenous equilibrium.
The equilibrium constant, Kc, for the single-step reaction X(g) + Y(g) ⇌ XY(g) is 3.0×103. Which one of the following is true?
For the given reaction, provide the Kc expression and determine if it is homogenous or heterogenous:
2 Hg(l) + O2(g) ⇌ 2 HgO(s)
Identify the incorrect statement.
Consider the following equilibrium:
H2O (l) ⇌ H2O (g)
At 70°C, what is the value of Kp for this reaction?
The equilibrium constant for the following decomposition reaction at 75.0 °C is 2.73.
NH3BF3(s) ⇌ NH3(g) + BF3(g)
What is the minimum amount of NH3BF3(s) in grams that has to be added to a 0.350 L flask in order to reach equilibrium?
Like naphthalene balls, 1,4-Dichlorobenzene (para-dichlorobenzene) balls are used to kill moth larvae by their slight sublimation at room temperature. A reasonable amount of these were left exposed in a 5.0 m by 5.0 m by 5.0 m room at 25 °C. Assuming that these spheres are pure solid para-dichlorobenzene and that the Kc value for the sublimation reaction is 2.72×10−13 at 25 °C, determine the number of gaseous para-dichlorobenzene molecules present in the room at equilibrium.

Calculate the equilibrium constant Kp for the following reaction at 373.15 K:
2 NO2(g) ⇌ N2(g) + 2 O2(g)
Use the following reactions and their Kc at the same temperature:
NO(g) + 1/2 O2(g) ⇌ NO2(g) Kc = 8.0×104
2 NO(g) ⇌ N2(g) + O2(g) Kc = 5.0×1024
The following reaction is a vital step in the metabolism of glucose: glucose + ATP ⇌ glucose-6-phosphate + ADP
Determine the equilibrium constant for the above reaction using the related equilibrium constants:
glucose + Pi ⇌ glucose-6-phosphate, K = 3.114 × 10–3
ATP ⇌ ADP + Pi, K = 2.716 × 105
Write the expression for the equilibrium constant, Kp, and provide the equation that relates Kp to Kc for the reaction C2H6(g) + Cl2(g) ⇌ C2H5Cl(s) + HCl(g).
