Equilibrium Question 639
Question: In the reaction, $ A+B $ ⇌ $ 2C $ , at equilibrium, the concentration of A and B is $ 0.20mol{l^{-1}} $ each and that of C was found to be $ 0.60mol{l^{-1}} $ . The equilibrium constant of the reaction is [MH CET 2000]
Options:
A) 2.4
B) 18
C) 4.8
D) 9
Show Answer
Answer:
Correct Answer: D
Solution:
$ A+B $ ⇌ $ 2,C $
$ K_{c}=\frac{{{[C]}^{2}}}{[A][B]}=\frac{{{[0.6]}^{2}}}{[0.2][0.2]}=9 $
