The equilibrium system n2o4(g) 2no2(g) was established in a 1.00-liter vessel. upon analysis, the following information was found: [no2] = 0.500 m; [n2o4] = 0.0250 m. what is the value of keq?
a. 20.
b. 0.050
c. 10.0
d. 0.10

c)  10.0

Explanation:

The balanced equilibrium reaction will be,

Concentration of at equilibrium = 0.500 M

Concentration of at equilibrium  = 0.0250 M

The expression for equilibrium reaction will be,

Now put all the given values in this expression:

Therefore, the equilibrium constant is 10.0.
