question_answer
In a reaction\[A+B~\rightleftharpoons C+D\], the initial concentrations, of A and B were 0.9 mol. \[d{{m}^{-3}}\]each. At equilibrium the concentration of D was found to be 0.6 mol \[d{{m}^{-3}}\]. What is the value of equilibrium constant for the reaction
A)8
B)4
C)9
D)3
Correct Answer:
B
Solution :
[a] Initial At eqm. \[{{K}_{c}}=\frac{0.6\times 0.6}{0.3\times 0.3}=4\]
