The equilibrium pressures below were observed at a certain temperature for the following reaction.

PNH₃ = 3.1 ✕ 10⁻² atm
PN₂ = 8.5 ✕ 10⁻¹ atm
PH₂ = 3.1 ✕ 10⁻³ atm
Calculate the value for the equilibrium constant at this temperature.

37 950

Explanation:

Thinking process:

Let's consider a reversible gaseous reaction:

As all the reactants and products are gaseous, the reaction is a homogeneous reaction. In other words, the reactants and and products are in the same phase.

The equilibrium constant is expressed in terms of partial pressures like this:

using the formula for the reaction in the question:

Kp = (3.1 ✕ 10⁻² atm)²/ (8.5 ✕ 10⁻¹ atm) (3.1 ✕ 10⁻³ atm)³

     = 37 950

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
