Consider the reaction below in a closed flask. At 200 o C, the equilibrium constant (Kp) is 2.40 × 103 . 2 NO (g)  N2 (g) + O2
olga55 [171]

Explanation:

Since, the given reaction is as follows.

       2NO(g) \rightleftharpoons N_{2}(g) + O_{2}(g)

Initial:    36.1 atm                 0          0

Change:    2x                      x           x

Equilibrium: (36.1 - 2x)       x            x

Now, expression for K_{p} of this reaction is as follows.

            K_{p} = \frac{[N_{2}][O_{2}]}{[NO]^{2}}

As the initial pressure of NO is 36.1 atm. Hence, partial pressure of O_{2} at equilibrium will be calculated as follows.

              K_{p} = \frac{[N_{2}][O_{2}]}{[NO]^{2}}

        2.40 \times 10^{3} = \frac{x \times x}{(36.1 - 2x)^{2}}

                 x = 18.1 atm

Thus, we can conclude that partial pressure of O_{2} at equilibrium is 18.1 atm.

Answer:

Wet climates obviously have more water than driers climates. Metals, when subject to water have the tendency to oxidize rust. Therefore, if water is barely present in a climate, then oxidation is also least likely to occur.

The Mass of ice is 69.12g.

What is mass?

It is a dimensionless quantity that expresses a particle or object's mass. The accepted unit of mass under the International System (SI) is the kilogram.

What is temperature?

Temperature is a measure of the average kinetic energy of the particles inside an object. The temperature increases cause these particles to move more quickly. It is possible to measure temperature using a thermometer or a calorimeter.

first calculate the amount of heat as follows;

q= mass of water C= (0°C-55°C)

=100.0g (4.186J/g°c) (-55°C)

=-23023J

Heat lost by water is gained by ice,

-q=m*ΔH

-23023J= m*333J/g

= 69.12g

Therefore, Mass of ice is 69.12g.
