Concentration Definition. In chemistry, concentration refers to the amount of a substance per defined space. Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration usually is expressed in terms of mass per unit volume.

Since you have not included the given reaction, I am going to explain you how to solve these kind of problems.
1) The chemical equilibrium is a
dynamic process. It means that in an equilibrim reaction there are two rectaions,
the forward reaction and the reverse reaction whose velocities are the same.
2) The general equation of a a chemical reaction in equlibrium is:
aA + bB ⇄ cC + dDWhere A and B are the reactants, C and D are the products, and a, b, c, d, are the coefficientes in the
balanced equation.3) So, the
equilibrium law is:
![Keq= \frac{C]^c[D]^d}{[A]^a[B]^b}](https://tex.z-dn.net/?f=Keq%3D%20%5Cfrac%7BC%5D%5Ec%5BD%5D%5Ed%7D%7B%5BA%5D%5Ea%5BB%5D%5Eb%7D%20)
Where Keq is the constant of equilibrium
4) To complete the explanation, I am going to deal with an
example:
i) Consider the equlibrium reaction between hydrogen and iodine:
H₂ (g) + I₂(g) ⇄ 2HI(g)ii) The forward reaction is H₂ (g) + I₂(g) → 2HI(g)
iii) The reverse reaction is 2HI (g) → H₂ (g) + I₂(g)
iv) The
law of equilibrium is:
Gas tanks are highly pressurized and oxygen is highly flammable in the gaseous state
