57.) The ozone, O3, of the stratosphere can be decomposed by reac- tion with nitrogen oxide...
The depletion of ozone (O3) in the stratosphere has been a matter of great concern among scientists in recent years. It is believed that ozone can react with nitric oxide (NO) that is discharged from the high-altitude jet plane, the SST. The reaction is O3 + NO longrightarrow O2 + NO2 If 0.845 g of O3 reacts with 0.687 g of NO, how many grams of NO2 will be produced? g NO2 Which compound is the limiting reagent? nitric oxide...
Regular flights of supersonic aircraft in the stratosphere are of concern because such aircraft produce nitric oxide, NO, as a byproduct in the exhaust of their engines. Nitric oxide reacts with ozone, and it has been suggested that this could contribute to depletion of the ozone layer. NO (g) + O3 (g) ------> NO2 (g) + O2 (g) The reaction is first order with respect to both NO and O3 concentrations and has a rate constant of 2.20 x 107...
