Equilibrium Question 642
Question: For the reaction $ H_2+I_2=2HI $ ,the equilibrium concentration of $ {H_{2,}},,I_2 $ and $ HI $ are 8.0, 3.0 and 28.0 mol per litre respectively, the equilibrium constant of the reaction is [BHU 2000; CBSE PMT 2001]
Options:
A) 30.66
B) 32.66
C) 34.66
D) 36.66
Show Answer
Answer:
Correct Answer: B
Solution:
$ K_{c}=\frac{{{[HI]}^{2}}}{[H_2][I_2]}=\frac{{{(28)}^{2}}}{8\times 3}=32.66 $
