D) O-O

The higher the difference in electronegativities of the two atoms, the more polar it is. Although oxygen is a very electronegative atom, it is bonded to itself which would make it a nonpolar bond.

Plz help, I will give brainliest.

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

Lower temperature

Let's verify

  • Pressure=P
  • volume=V
  • Temperature=T

As per Boyles law

\\ \rm\Rrightarrow V\propto \dfrac{1}{P}

As per Charles law

\\ \rm\Rrightarrow V\propto T

\\ \rm\Rrightarrow T\propto \dfrac{1}{P}

So

At higher altitudes lower the pressure so lower the temperature
