Energy Profile and Rate Law for SN2 Reactions Reaction Order

1 Energy Profile and Rate Law for SN2 Reactions Reaction Order [Pg.60]

Do you remember the definition of an elementary reaction (Section 1.7.1) The SN2 reaction is such an elementary reaction. Recognizing this is a prerequisite for deriving the rate law for the Sn2 reaction, because the rate law for any elementary reaction can be obtained directly from the reaction equation. [Pg.60]

The overall reaction rate is the rate of product formation (/[product]/(ft or a starting material consumption rate -d[starting material]/eft. The following applies unless the stoichiometry requires an additional multiplier [Pg.61]

With the help of the rate laws that describe the elementary reactions involved, it is possible to derive Equation 2.4 [Pg.61]

The rate of product formation or starting material consumption is equal to the product of the rate constant k for this elementary reaction and the concentration of all starting materials involved, including any catalyst. It turns out that all elementary reactions are either first- or second-order reactions. [Pg.61]
