13.4 Exercise 9

Avg difficulty 2.5

A sample of ammonium chloride was heated in a closed container.

NH4Cl(s)⇌NH3(g)+HCl(g)\text{NH}_{4} \text{Cl} \left(s\right) \rightleftharpoons \text{NH}_{3} \left(g\right) + \text{HCl} \left(g\right)

At equilibrium, the pressure of NH3(g) was found to be 1.75 atm. What is the value of the equilibrium constant KP for the decomposition at this temperature?
