Answer: Equilibrium constant is 0.70.
Explanation:
Initial moles of = 0.35 mole
Volume of container = 1 L
Initial concentration of
Initial moles of = 0.40 mole
Volume of container = 1 L
Initial concentration of
equilibrium concentration of [/tex]
The given balanced equilibrium reaction is,
Initial conc. 0.35 M 0.40M 0 0
At eqm. conc. (0.35-x) M (0.40-x) M (x) M (x) M
The expression for equilibrium constant for this reaction will be,
we are given : (0.35-x)= 0.18
x = 0.17
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is 0.70.
