A sample of only solid ammonium chloride was heated in a 1.00-L container at 500.°C:
NH4Cl(s) NH3(g) + HCl(g)
a. 7.6 × 10^−4
b. 1.2 × 10^4
c. 4.8 × 10^−2
d. 1.9 × 10^2
e. 1.8 × 10^−3
Answer: a. 7.6 × 10^−4
NH4Cl(s) NH3(g) + HCl(g)
At equilibrium, the pressure of NH3(g) was found to be 1.75 atm. What is the equilibrium constant, Kc, for the decomposition at this temperature?
