EQUILIBRIUM PROBLEM
ANSWER
 

Exercises

  Pure NOCl gas was heated at 240 oC in a 1.00 L container. At equilibrium the total pressure was 1.00 atm and the NOCl pressure was 0.64 atm.
2 NOCl(g) 2NO(g) + Cl2(g)
  1. Calculate the partial pressures of NO and Cl2 in the system.
  2. Calculate the equilibrium constant Kp

 
 

Answer

  1. Partial pressure NO = 0.24 atm, Partial pressure Cl2 = 0.12 atm

  2. Kp=1.69 x 10-2

 

Explanation

 

The partial pressures of the product gases must be determined using stoichiometry!
