Answer: 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
