CHEM 1A03 LECTURE 7: OCT 15 20 – DYNAMIC CHEMICALEQUILIBRIUM
• Ostwald Process: often used to produce nitric acid from the oxidation of ammonia and its
dissolution in water.
• When finding a net K value for a multi-step rxn, if you need to multiple one equation by a
coefficient, the K value for that step in the reaction is to the power of that coefficient.
• Nitrogen dioxide is a toxic, reactive and gas irritant that can dimerize to form dinitrogen
tetraoxide (N2O4). K=11.4 at 25C. Gas in atmosphere that contributes to pollution.
Endothermic, which explains why it dimirizes in hot weather to create smog.
• K expression includes activity of all reactants in products in aqueous or
