Equilibrium Question 637
Question: Equilibrium concentration of $ HI,,I_2 $ and $ H_2 $ is $ 0.7,,0.1 $ and $ 0.1,M $ respectively. The equilibrium constant for the reaction $ I_2+H_2 $ ⇌ $ 2HI $ is [JIPMER 2000]
Options:
A) 36
B) 49
C) 0.49
D) 0.36
Show Answer
Answer:
Correct Answer: B
Solution:
$ K_{c}=\frac{{{[HI]}^{2}}}{[H_2][I_2]}=\frac{{{[0.7]}^{2}}}{[0.1][0.1]}=49 $
