Equilibrium Question 625
Question: The equilibrium concentration of $ X,,Y $ and $ YX_2 $ are 4, 2 and 2 moles respectively for the equilibrium $ 2X+Y $ ⇌ $ YX_2 $ . The value of $ K_{c} $ is [EAMCET 1990]
Options:
A) 0.625
B) 0.0625
C) 6.25
D) 0.00625
Show Answer
Answer:
Correct Answer: B
Solution:
$ K_{c}=\frac{[YX_2]}{{{[X]}^{2}}[Y]}=\frac{2}{4\times 4\times 2}=\frac{1}{16}=0.0625 $ .
