Chemical kinetics: the area of chemistry that concerns reaction rate. Main concerns of chemical kinetics: 1) Reaction rate: the factors that determines the rate of reaction and rate law
2) Reaction mechanism: the series of steps by which a reaction takes place. 3) structure-dependence of reactivity The correlation between molecular structure and reaction ability
2) Reaction mechanism: the series of steps by which a reaction takes place. 3) structure-dependence of reactivity. The correlation between molecular structure and reaction ability
Reaction mechanism and elementary reaction Reaction mechanism /reaction pathway the detailed way by which the reactants are converted into products, or the series of steps by which a reaction takes place
the detailed way by which the reactants are converted into products, or the series of steps by which a reaction takes place. Reaction mechanism and elementary reaction Reaction mechanism / reaction pathway detailed way series of steps
H2+12=2HI Kinetic experiments suggest that this reaction occurring as follows 1)2=2I 并不是相当然的 也不是表面的东西 2)2I+H2=2HI
H2 + I2 = 2 HI Kinetic experiments suggest that this reaction occurring as follows: 1) I2 = 2I 2) 2I + H2 = 2HI 并不是相当然的, 也不是表面的东西
H+ Br=2 HBr 1) Br2=2 Br 2) Br+ H2=HBr+H 3)H+ Br2=HBr+ Br 4)H+ HBr= h2+ Br 5)2 Br= Br
H2 + Br2 = 2 HBr 1) Br2 = 2 Br 2) Br + H2 = HBr + H 3) H + Br2 = HBr + Br 4) H + HBr = H2 + Br 5) 2 Br = Br2 More complicate!
