Nitric Oxide Production from Synthesized Ruthenium (III) Porphyrins
... One of the regulatory processes of nitrite in mammalian systems is by its reaction with iron found in porphyrin systems. One important reaction is the production of an Iron (II) nitrosyl from Iron (III) and a nitrite ion. This research investigated Ru (III) porphyrin systems, as it is a possible can ...

Power Point for Equilibrium
... • At some time, the color stops changing and we have a mixture of N2O4 and NO2. • Chemical equilibrium is the point at which the rate of the forward reaction is equal to the rate of the reverse reaction. At that point, the concentrations of all species are constant. • Using the collision model: – as ...
