Answer:
ΔS Rx = -120, 5 J/K
Explanation:
The ΔS in a reaction is defined thus:
ΔS Rx = ∑ n S°products - ∑ m S°reactants
For the reaction:
N₂(g) + 2 O₂(g) → 2NO₂(g)
ΔS Rx = 2 mol × 240,5 
- [ 1 mol × 191,5 + 2 mol × 205,0 ]=
<em>ΔS Rx = -120, 5 J/K</em>
A negative value in ΔS means a negative entropy of the process. Doing this process entropycally unfavorable.

<h3>What is nitrogen monoxide?</h3>
Nitrogen oxide, also known as nitrogen monoxide or nitric oxide, is an inert gas with the chemical formula NO. It is one of the main nitrogen oxides. Free radical nitric oxide (•N=O or •NO) possesses an unpaired electron, which is commonly indicated by a dot in its chemical formula. As a heteronuclear diatomic molecule, nitric oxide also contributed to the development of early modern theories of chemical bonding.
Nitric oxide is a chemical compound that occurs in combustion systems and can be produced by lightning during thunderstorms. It is a crucial intermediate in industrial chemistry. In many physiological and pathological processes in animals, including humans, nitric oxide serves as a signaling molecule.
