An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition).
A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.
Bases can be thought of as the chemical opposite of acids. A reaction between an acid and base is called a neutralization reaction.
The strength of an acid refers to its ability or tendency to lose a proton; a strong acid is one that completely dissociates in water.

At equilibrium, the concentrations in this system were found to be [N2]=[O2]=0.200 M and [NO]=0.400 M.
Kipish [7]

Answer:

The concentration in equilibrium of NO is 0,550M.

Explanation:

For the reaction:

N₂(g) + O₂(g) ⇄ 2NO

The equilibrium constant is defined as:

k = [NO]² / [N₂][O₂] <em>(1)</em>

Replacing for the concentrations in equilibrium:

k = (0,400M)² / (0,200M)(0,200M)

<em>k = 4,000</em>

If you add more NO until 0,700M, the equilibrium concentrations will be:

[NO] = 0,700M-2x

[N₂] = 0,200M+x

[O₂] = 0,200M+x

Replacing in (1)

4,000 =  (0,700M-2x)² / (0,200M+x)²

4,000 =  4x²- 2,8x + 0,49 / x² + 0,4x + 0,04

4x² + 1,6x + 0,16 = 4x²- 2,8x + 0,49

4,4x = 0,33

x = 0,075M

That means that concentration in equilibrium of NO is:

[NO] = 0,700M - 2×0,075M = <em>0,550M</em>

I hope it helps!
