Using the reactions given, calculate equilibrium constants designated for A-F. R

Question

Using the reactions given, calculate equilibrium constants designated for A-F. Rank these values of equilibrium constant from the highest to the lowest. The temperature is 50C.

H2(g) + I2(s) <==> 2 HI(g)

2 HBr(g) <==> H2(g) + Br2(g) KP = 514.3 KP = 0.0077

H2(g) + I2(s)<==> 2 HI(g) Kc=

2 HBr(g)<==> H2(g) + Br2(g) Kc=

2 HI(g)<==> H2(g) + I2(s) Kp=

HBr <==> 12 H2(g) + 12 Br (g) Kp=

2 HBr(g) + I2(s) <==> 2 HI(g) + Br2(g) Kp=

4 HI(g) <==> 2 H2(g) + 2 I2(s) Kp=

Highest 1_______ 2________ 3________ 4________ 5________ 6________ Lowest Explain your reasoning below. (Show calculations if needed.)

Explanation / Answer

H2(g) + I2(s)<==> 2 HI(g) Kc= 514.3 --------------> 1

2 HBr(g)<==> H2(g) + Br2(g) Kc = 0.0077 ---------------> 4

2 HI(g)<==> H2(g) + I2(s) Kp = 0.00194   ---------------> 5

HBr <==> 12 H2(g) + 12 Br (g) Kp = 0.0877 ----------------> 3

2 HBr(g) + I2(s) <==> 2 HI(g) + Br2(g) Kp = 3.96   ---------------> 2

4 HI(g) <==> 2 H2(g) + 2 I2(s) Kp = 3.78 x 10^-6 ----------------> 6
