Plz help, I will give brainliest.

The value of is 2

Explanation:

Moles of   = 1.0 mole  

Volume of solution = 1.00 L

Initial concentration of =

Equilibrium concentration of =  

The given balanced equilibrium reaction is,

Initial conc.          1.0 M            0 M

At eqm. conc.     (1.0-x) M      (2x) M

The expression for equilibrium constant for this reaction will be,

Given : 2x = 1.0

x= 0.5

Now put all the given values in this expression, we get :

Thus the value of is 2
