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.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
