At 298 k, the equilibrium concentration of o2 is 1.6 x 10-2 m, and the equilibrium concentration of o3 is 2.86 x 10-28 m. what is the equilibrium constant of the reaction at this temperature?

The equilibrium constant of the reaction at this temperature is

Explanation:

Equilibrium is the condition at which the reactants and products concentration is constant.

At equilibrium rate of the forward reaction = rate of the backward or reverse reaction  

The Chemical equilibrium is  

is the equilibrium constant and is defined as products concentration over reactant concentration and the coefficient is raised to its power. Thus we have the expressed as

Plugging in the values given in the question, we have

(Answer)

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
