Equilibrium Question 604

Question: On a given condition, the equilibrium concentration of HI,,H2 and I2 are 0.80, 0.10 and 0.10 mole/litre. The equilibrium constant for the reaction H2+I22HI will be [MP PET 1986]

Options:

A) 64

B) 12

C) 8

D) 0.8

Show Answer

Answer:

Correct Answer: A

Solution:

H2+I2 ⇌ 2HI; [HI] = 0.80, [H2]=0.10 , [I2]=0.10

Kc=[HI]2[H2][I2]=0.80×0.800.10×0.10=64
