Kinetics
- Rate=k x [A]^m x [B]^n
- Rate = mol dm^-3 s^-1
- The rate of the reaction is
defined as the change in
conc. with unit time
- The rate of the reaction is
defined as the change in
conc. with unit time
- k = rate constant
- The constant of proportionality
in the rate expression
- The units depend on the
orders of the reactants
- The constant of proportionality
in the rate expression
- [A] / [B] = concentration of reactants
- mol dm^-3
- mol dm^-3
- m / n = orders of reaction
with respect to the
reactants (0, 1 or 2)
- Rate = mol dm^-3 s^-1
- 0th order
- The rate is not affected by the
concentration of a species
- The rate is not affected by the
concentration of a species
- 1st order
- The rate is directly proportional
to the concentration of a species
- The rate is directly proportional
to the concentration of a species
- 2nd order
- The rate is proportional to the
square of the concentration of a
species
- The rate is proportional to the
square of the concentration of a
species
- Increasing temperature always
increases the rate of reaction and
the value of k
- Rate determining step
- The slowest step in the reaction
mechanism. It governs the rate
of the overall reaction
- The species in the rate equation are the
reactants involved in reactions occuring before
the rate determining step
- If a reactant doesn't appear in the rate
equation, it won't be involved in the
rate-determining step
- The slowest step in the reaction
mechanism. It governs the rate
of the overall reaction
