At 1000 K, a sample of pure NO2 gas decomposes. 2 NO2(g) equilibrium reaction arrow 2 NO(g) + O2(g) The equilibrium constant KP
kirill115 [55]

<u>Answer:</u> The pressure of NO and NO_2 in the mixture is 0.58 atm and 0.024 atm respectively.

<u>Explanation:</u>

We are given:

Equilibrium partial pressure of O_2 = 0.29 atm

For the given chemical equation:

                   2NO_2(g)\rightleftharpoons 2NO(g)+O_2(g)

Initial:              a

At eqllm:        a-2x          2x          x

Calculating for the value of 'x'

\Rightarrow x=0.29

Equilibrium partial pressure of NO = 2x = 2(0.29) = 0.58 atm

Equilibrium partial pressure of NO_2 = a - 2x = a - 2(0.29) = a - 0.58

The expression of K_p for above equation follows:

K_p=\frac{p_{O_2}\times (p_{NO})^2}{(p_{NO_2})^2}

We are given:

K_p=158

Putting values in above expression, we get:

158=\frac{0.29\times (0.58)^2}{(a-0.58)^2}\\\\a=0.555,0.604

Neglecting the value of a = 0.555 because it cannot be less than the equilibrium concentration.

So, a=0.604

Equilibrium partial pressure of NO_2 = (a - 0.58) = (0.604 - 0.58) = 0.024 atm

Hence, the pressure of NO and NO_2 in the mixture is 0.58 atm and 0.024 atm respectively.

The growth of the plants that the animal used for food could not keep up with the needs of the population. there was so little f
WARRIOR [948]

In this case, the population has exceeded the available food, thus causing a decline in the population.

<h3>What is carrying capacity?</h3>

It is the maximum population size that an ecosystem can sustain based on the resources that it has.

Above the carrying capacity, resources become extremely limited and competition becomes stiff in the population. Thus, the population declines.

Below the carrying capacity, resources are abundant and the population grows. Most of the time, a mature population hovers around the carrying capacity of the ecosystem.
