elixir [45]

Answer : The partial pressure of $NO_2$ is, 12.34 atm

Explanation :

For the given chemical reaction:

$N_2O_4(g)\rightleftharpoons 2NO_2(g)$

The expression of $K_p$ for above reaction follows:

$K_p=\frac{(P_{NO_2})^2}{P_{N_2O_4}}$ ........(1)

The equilibrium reaction is:

$N_2O_4(g)\rightleftharpoons 2NO_2(g)$

Initial x 0

At eqm (x-y) 2y

Putting values in expression 1, we get:

$70.9=\frac{(2y)^2}{(x-y)}$ ..............(2)

As we are given that, 25.8 % of $N_2O_4$ remains at equilibrium. That means,

$25.8\% \times x=(x-y)$

$\frac{25.8}{100}\times x=(x-y)$

$0.258\times x=(x-y)$

$0.742x=y$ ..............(3)

Now put equation 3 in 2, we get the value of 'x'.

$70.9=\frac{(2\times 0.742x)^2}{(x-0.742x)}$

$x=8.31$

Now put the value of 'x' in equation 3, we get:

$0.742x=y$

$0.742\times 8.31=y$

$y=6.17$

Now we have to calculate the new partial pressure of $NO_2$ at equilibrium.

Partial pressure of $NO_2$ = (2y) = (2\times 6.17) = 12.34 atm

Hence, the partial pressure of $NO_2$ is, 12.34 atm

How does energy from the some travel to earth

Finger [1]

Answer:

Bye the way, u welcome ;)

In heat transfer by radiation, energy is carried by electromagnetic waves from a starting point to the space surrounding it and does not involve contact with matter. The other forms of heat transfer cannot produce any of the energy that arrives to Earth through the vacuum of space.
