Example Questions

Example Question #51 : Chemical Equilibrium

Calculate the equilibrium constant for $2 C(g) \Leftrightarrow A (g) + B (g)$ given the following information:

$A (g) + B (g) \Leftrightarrow 2 C (g)$ $K_1 = 4.39 x 10^{-3}$

$2 C(g) \Leftrightarrow D (g) + E (g)$ K_2 = 1.15 x 10^4

Possible Answers:

$3.14 \, x \, 10^{-3}$

$2.28 \, x \, 10^2$

$1.14\, x\, 10^2$

11.4

22.8

Correct answer:

$2.28 \, x \, 10^2$

Explanation:

$2 C \Leftrightarrow A + B$ K = 1/K_1= 228

Example Question #52 : Chemical Equilibrium

Calculate the equilibrium constant for $A (g) + B (g) \Leftrightarrow D (g) + E (g)$ given the following information:

$A (g) + B (g) \Leftrightarrow 2 C (g)$ $K_1 = 4.39 \, x \, 10^{-3}$

$2 C(g) \Leftrightarrow D (g) + E (g)$ $K_2 = 1.15 \, x \, 10^4$

Possible Answers:

73.2

25.3

50.5

0.143

15.8

Correct answer:

50.5

Explanation:

$A + B \Leftrightarrow 2 C$ $K_1 = 4.39 x 10^{-3}$

$2C \Leftrightarrow D + E$ $K_2 = 1.15 x 10^{-4}$

$K = K_1 K_2 = (4.39 x 10^{-3}) (1.15 x 10^{-4}) = 50.5$

Example Question #141 : Reactions And Equilibrium

Calculate the equilibrium constant for $N_2 (g) + O_2 (g) + Cl_2 (g) \Leftrightarrow 2 \: NOCl$ given the following information:

$\frac{1}{2}N_2 + O_2(g) \Leftrightarrow NO_2 (g)$ $K_1 = 1.0 \, x \, 10^{-9}$

$NOCl(g) + \frac{1}{2} O_2 (g) \Leftrightarrow NO_2Cl$ $K_2 = 1.1 \, x\, 10^2$

$NO_2 (g) + \frac{1}{2} Cl_2 \Leftrightarrow NO_2Cl$ K_3 = 0.3

Possible Answers:

$5 \, x \, 10^{-10}$

$3\, x\, 10^{-3}$

$7\, x\, 10^{-24}$

$7\, x\, 10^{-8}$

Correct answer:

$7\, x\, 10^{-24}$

Explanation:

$2 (1/2 N_2 + O_2 \Leftrightarrow 2 NO_2 )$ $K = K_1^2 = 1 x 10^{-18}$

$2 (NO_2Cl \Leftrightarrow NOCl + 1/2 O_2)$ $K = (1/K_2)^2 = 8.3 x 10^{-5}$

$2 (NO_2 + 1/2 Cl_2 \Leftrightarrow NO_2Cl)$ K = K_3^2 = 0.09

$K = (1 x 10^{-18}) (8.3 x 10^{-5}) (0.09) = 7 x 10^{-24}$

Example Question #51 : Chemical Equilibrium

Calculate the equilibrium constant for $2 NH_3 (g) + 3 I_2 (g) \Leftrightarrow N_2 (g) + 6 HI (g)$ given the following information:

$N_2 (g) + 3 H_2 (g) \Leftrightarrow 2 NH_3(g)$ K_1 = 0.50

$H_2 (g) + I_2 (g) \Leftrightarrow 2 HI (g)$ K_2 = 50

Possible Answers:

$3.2 x 10^{-3}$

1.5 x 10^3

5.6 x 10^4

2.8 x 10^6

2.5 x 10^5

Correct answer:

2.5 x 10^5

Explanation:

$2 NH_3 \Leftrightarrow N_2 + 3 H_2$ K = 1/K_1 = 2

$3 ( H_2 + I_2 \Leftrightarrow 2 HI)$ K = K_2^3 = 1.25 x 10^5

K = (2) (1.25 x 10^5) = 2.5 x 10^5

1.21

0.25

0.05

0.01

Correct answer:

0.02

Explanation:

$2 HI \Leftrightarrow H_2 + I_2$ K = 1/K_1 = 0.02
