Q. In which one of the following gaseous equilibria, $ {{K}_{p}} $ is less than $ {{K}_{c}} $ ?

CMC MedicalCMC Medical 2010

Solution:

$ {{K}_{p}}={{K}_{c}}{{(RT)}^{\Delta {{n}_{g}}}} $ $ \Delta {{n}_{g}}=-1 $ (For the reaction, $ 2S{{O}_{2}}+{{O}_{2}}\rightleftharpoons 2S{{O}_{3}} $ ). Thus, for this reaction, $ {{K}_{p}} $ is less than $ {{K}_{c}} $ .
