Answer: The value of K_c is 2

Explanation:

Moles of  N_2O_4 = 1.0 mole  

Volume of solution = 1.00 L

Initial concentration of N_2O_4 = \frac{1.0mol}{1.00L}=1.0M

Equilibrium concentration of NO_2 = \frac{1.0mol}{1.00L}=1.0M  

The given balanced equilibrium reaction is,

                            N_2O_4(g)\rightleftharpoons 2NO_2(g)

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,

K_c=\frac{[NO_2]^2}{[N_2O_4]}

Given : 2x = 1.0

x= 0.5

Now put all the given values in this expression, we get :

K_c=\frac{(1.0)^2}{(1.0-0.5)}

K_c=2

Thus the value of K_c is 2

Why can water dissolve many ionic compounds
ludmilkaskok [199]
To dissolve an ionic compound, the water molecules must be able to stabilize the ions that result from breaking the ionic bond. Water is a polar molecule. It has a permanent dipole. ... The negative ions have several water molecules around them, all with their H atoms close to the negative ion
