3.4.1 Kinetics
Simple rate equations
· 0 order
o Changing the initial concentration of a reactant has no effect on the initial rate of reaction
· 1st order
o When the initial concentration of reactant is changed by X, the initial rate of reaction is changed by X too
· 2nd order
o When the initial concentration of reactant is increased by X, the initial rate of reaction is increased by X2
· Overall order= the sum of the individual orders of the reactants
Determining the rate equation
Rate=k [A]m [B]n
· Where m and n represent the orders of the reaction with respect to A and B
· Rate=k[A][C]
o A + B +2C…
