Nitrogen dioxide is produced from the oxidation of nitrogen
monoxide. The reaction is exothermic .
2 NO(g) + O2(g) → 2 NO2(g)
A proposed mechanism for this reaction is 2 NO(g) ⇌ N2O2(g)
(fast, equilibrium)
N2O2(g) + O2(g) → 2 NO2(g) (slow)
Draw a diagram for the reaction energy that is consistent with
this proposed mechanism?
In the laboratory you are asked to make
a 0.163 m ammonium
bromide solution
using 250 grams of water.
How many grams of ammonium
bromide should you add?
