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 high-altitude jet planes. The reaction is
If 0.740 g of O3 reacts with 0.670 g of NO, how many grams of NO2 will be produced? Which compound is the limiting reactant? Calculate the number of moles of the excess reactant remaining at the end of the reaction.
Chemistry 210 Chapter 4 9/26-9/30 Slide 1: Reactions: chlorination of methane -entropy can be neglected in this reaction -this is not the case for every reaction Slide 2: BDE -all numbers are positive -breaking bonds cost energy Slides 4-6 -the grey boxed reactions are favored because of the amount of energy the need/release when compared to other reactions that could occur Slide 10: Stereochemistry of radical reactions -equal in energy -no optical activity Slide 11: Stereochemistry of radical reactions -not equal in energy -has optical activity -enantiomeric excess Slide 12: Selectivity -Br prefers to abstract secondary H 80:1 -reacts 80x faster Slide 13: Origins of selectivity -primary H is stronger bond (according to BDE) -secondary H is easie
