reaction rateZoomA-Z

The reaction rate defines how fast or slow a chemical reaction takes place. The rate is expressed as the actual, i.e. the rate at a particular instant of time, change of concentration per unit of time based on stoichiometric turnover. For the reaction

νAA+νBB+νPP+νQQ+

the reaction rate relates to reaction-based concentration changes as follows:

r=-1νAd[A]dt=-1νBd[B]dt==+1νPd[P]dt=+1νQd[Q]dt=

Recommended Learning Units

SN/E Competition - Role of the TemperatureLevel 320 min.

ChemistryOrganic ChemistrySubstitution Reactions

First, this learning unit describes the mechanistic reasons for the competition of elimination and nucleophilic substitution. Then, the influence of the reaction temperature on the SN2/E2 competition as well as the SN1/E1 competition is discussed.

SN/E Competition - SN1/E1 CompetitionLevel 330 min.

ChemistryOrganic ChemistrySubstitution Reactions

First, this learning unit describes the mechanistic reasons for the competition of elimination and nucleophilic substitution. Then, the different parameters that influence the SN1/E1 competition are discussed. After working through the learning unit, one should be able to predict, depending on given parameters, the predominant mechanism of a reaction or to choose the parameters of a reaction, so that a mechanism desired actually mainly occurs, respectively.
