4 mol of X and 4 mol of V are mixed together. For the reaction \[X+Y\,\,\,P+Q\,\], 2 mol of P and Q are formed at equilibrium. The equilibrium constant for the reaction will be

A)  \[\frac{1}{4}\]                         

B)  \[\frac{1}{2}\]

C)  1                                

D)  4

Correct Answer: C

Solution :

Equilibrium constant is\[{{K}_{c}}=\frac{[C][D]}{[A][B]}=1\]
