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):}`
Calculate `G` of the above decomposition reaction at `298K`.
