1. How many covalent bonds are expected to form from phosphorus in order to obey the octet rule?
Grace [21]
To satisfy the octet rule, there has to be eight electrons in phosphorus's outermost shell. Phosphorus has five electrons in its valence shell, fluorine has seven. This means that phosphorus would have to bond to three fluorine atoms in order to have eight electrons in its valence shell without breaking the octet rule in any one of the fluorine atoms.

The equilibrium constant for the following equation:
Mkey [24]

From the calculation, the partial pressure of Cl2 is 1.98 atm. Option B

<h3>What is the equilibrium constant?</h3>

The term equilibrium constant refers to the value that shows us the extent to which reactants are converted into products. We know that the equilibrium constant can only be obtained by the use of the equilibrium partial pressures of each of the species.

Thus we have;

K = p PCl3 . pCl2/pPCl5

p PCl3 = partial pressure of PCl3

pCl2 = partial pressure of Cl2

pPCl5 = partial pressure of PCl5

K = equilibrium constant

Substituting values;

1.05 =  0.463 *  pCl2/0.875

 pCl2 = 1.05  * 0.875/0.463

pCl2 = 1.98 atm
