Reaction stoichiometry, kinetics and thermodynamics ltbgt Nitrosyl chloride (NOCl), is a yellow gas that is most commonly encountered as a decomposition product of aqua regia. It is toxic and irritating to the lungs. On heating NOCl decomposes as 2NOClrarr2NO+Cl_(2). The enthalpy change (DeltaH) for the formation of 1 mole of Cl_(2) by the decomposition of NOCl is 75.3KJ between 100.K "to" 600K. The standard entropies (S^(@)_(298K)) of different species are as given below: {:("Substance",NOCl,NO,Cl_(2)),(S_(298K)^(@),264,211,223):} A gaseous mixture of NO,Cl_(2) and NOCl with partial pressures (in bar) 1.5,0.88 and 0.065 respectively was taken at 475K. Deduce whether the net reaction will lead to increase in NOCl concentration.
