Nitrogen monoxide and ozone react to form nitrogen dioxide and oxygen, like this: NO(g) + O3 → NO2 + O2

The reaction is exothermic. Suppose a mixture of NO, O3 NO and O2 has come to equilibrium in a closed reaction vessel. Predict the change.

The pressure of O2 will increase. Shift to the right.

The pressure of O3 will increase . Dhift to the left

Explanation:

The perturbations are:

The temperature is lowered. The pressure of O2 will

The temperature is raised. The pressure of O3 will:

We can Apply LeCh's principle and see the heat, ΔH, as a product of the reaction:

NO(g) + O3(g) → NO2(g) + O2(g) + ΔH

If temperature is lowered, the system will shift to the right in order to produce more heat doing:

The pressure of O2 will increase

In the other way, if temperature is raised, the system will shift to the left in order to decrease the amount of heat produced.

The pressure of O3 will increase

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

no but i do not usually comment or use my voice that much when it comes to social media
