Ray Of Light [21]
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.

The elementary reaction 2H2O(g)↽−−⇀2H2(g)+O2(g) proceeds at a certain temperature until the partial pressures of H2O, H2, and O2
jenyasd209 [6]

Answer:

1.742\times 10^{-5} is the value of the equilibrium constant at this temperature.

Explanation:

2H_2O\rightleftharpoons 2H_2+O_2

We are given:

Partial pressure of H_2O=p^o_{H_2O}=0.0750 atm

Partial pressure of H_2=p^o_{H_2}=0.00700 atm

Partial pressure of O_2=p^o_{O_2}=0.00200 atm

The expression of K_p for the given chemical equation is:

K_p=\frac{p^o_{H_2}^2\times p^o_{O_2}}{p^o_{H_2O}^2}

Putting values in above equation, we get:

K_p=\frac{(0.00700 atm)^2\times 0.00200 atm}{(0.0750 atm)^2}\\\\K_p=1.742\times 10^{-5}

1.742\times 10^{-5} is the value of the equilibrium constant at this temperature.
