Question: The compound A and B are mixed in equimolar proportion to form the products, $ A+B $ ⇌ $ C+D $ . At equilibrium, one third of A and B are consumed. The equilibrium constant for the reaction is [KCET 2004]
Options:
A) 0.5
B) 4.0
C) 2.5
D) 0.25
Show Answer
Answer:
Correct Answer: D
Solution:
$ K=\frac{[C][D]}{[A][B]}=\frac{\frac{1}{3}\times \frac{1}{3}}{\frac{2}{3}\times \frac{2}{3}}=\frac{1}{4}=0.25 $ So, $ K=0.25 $
