Question

The following reactions occur at 500 K. Arrange them in orderof increasing tendency to proceed to completion (i.e., leastcompletion -> greatest completion). 1. 2NOCl <---> 2NO+ Cl2    Kp = 1.7 x10-2 2. N2O4 <--->2NO2              Kp= 1.5 x 103 3. 2SO3 <---> 2SO2 +O2      Kp = 1.3 x10-5 4. 2NO2 <---> 2NO +O2      Kp = 5.9 x10-5 The following reactions occur at 500 K. Arrange them in orderof increasing tendency to proceed to completion (i.e., leastcompletion -> greatest completion). 1. 2NOCl <---> 2NO+ Cl2    Kp = 1.7 x10-2 2. N2O4 <--->2NO2              Kp= 1.5 x 103 3. 2SO3 <---> 2SO2 +O2      Kp = 1.3 x10-5 4. 2NO2 <---> 2NO +O2      Kp = 5.9 x10-5 4. 2NO2 <---> 2NO +O2      Kp = 5.9 x10-5

Explanation / Answer

We Know that :       The Kp value indicates that theReaction occur to what extent the formation of Products formationtakes place.          Kp = Kf / Kb i.e the Ratio of theForward Reaction / Backward Reaction      The Order of the Reactions is :             3 < 4 < 1 < 2 the Order of thecompletion of the Reaction.
