For systems 3, 4, 5 and 6, initial clusters were not observed which is much smaller than the critical cluster size (about 1 nm) at 40 ns. From the thermodynamic data, the large values of Gibbs free energy variation for cluster …
WebAccording to Le Chatelier’s principle, the formation of nitric oxide is favoured by high temperature. The temperature is thus maintained about 3000°C by the use of an electric arc. The nitric oxide· formed is immediately cooled to 1000°C as to prevent its decomposition. Nitric oxide further combines with oxygen to form nitrogen dioxide. Web1 jun. 2024 · With hot and conc. HNO 3 : When a highly conc. HNO 3 is added on Fe, a protective layer of ferrosoferric oxide (Fe 3 O 4) is formed and the iron becomes passive i.e. prevents the further action of acid on the iron metal. With moderately conc. (1:1) HNO 3 : Fe gives ferric salt and NO 2 gas.
WebA secondary air stream is introduced into the column to re-oxidize the NO that is formed in Reaction 3. This secondary air also removes NO 2 from the product acid.
