A 10g sample of soliid NH4CL is heated in a 5L container at 900 degrees C. At equilibrium the partial pressur

Question

of the NH3 is 1.2 atm. What is the equilibrium constant for this reaction? NH4Cl---->NH2 + HCl

Answer 1

For this reaction, the equilibrium constant will be given by:

Kp=P(NH3) P(HCl)

Since NH4Cl decomposes into one mole of NH3 and one mole of HCl, the partial pressure of HCl will equal the partial pressure of NH3. So, K will just be the product of those two pressures.

Answer 2
