Further explanationGiven:
The Kp for the reaction below is 1.49 · 10⁸ at 100.0°C
(a balanced reaction)
In an equilibrium mixture of the three gases.
p CO = p Cl₂ = 2.22 · 10⁻⁴ atm.
Question:
The partial pressure of the product, phosgene (COCl₂), is __ atm.
The Process:
Let us write the equilibrium constant in terms of pressure based on the reaction above.
We set p COCl₂ as the subject to be asked.
Substitute all the data above into the equation.
Thus, the partial pressure of the product, phosgene (COCl₂), is 7.34 atm.

Further explanation:
Chemical equilibrium:
The state where reactant concentration and product concentration become constant and do not change with time is known as equilibrium.The rate of forward and backward reactions becomes equal at equilibrium.
Equilibrium constant in pressure terms:
The ratio of partial pressures of products to partial pressures of reactants, both of these terms are raised to some power equal to their respective coefficients in a balanced chemical equation. It is denoted by
.
