One mole of SO3 was placed in a two litre vessel at a certain temperature. The following equilibrium was established in the vessel : 2SO3(g) ⇌ 2SO2(g)+O2 (g) The equilibrium mixture reacted with 0.2 mole KMnO 4 in acidic medium. Hence, Kc is : The most stable oxides of nitrogen will be : November 11, 2020 Category: Chapter 5 - Chemical Equilibrium (Level 1 and Level 2) , N Awasthi Physical Chemistry , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
