Ответ:
Answer : The equilibrium concentration of
is, 1.0 M
Explanation : Given,
Equilibrium concentration of
= 0.26 M
Volume of solution = 1.00 L
Equilibrium constant
= 4.0
The balanced equilibrium reaction will be,
The expression of equilibrium constant for the reaction will be:
From the reaction we conclude that the concentration of
and
are equal.
Let the concentration of
be 'X'.
So, concentration of
= X
Now put all the values in this expression, we get :
Thus,
The concentration of
at equilibrium = X = 1.0 M
The concentration of
at equilibrium = X = 1.0 M
