Random chem notes.

Hess' Law: No metter which pathway is taken in a reaction the enthalpy change remains the same.

If a catalyst is hot, more particles exceed the activation energy.

Aldehyde, Ketone = Functional group isomerism.


Initiation: Cl-Cl => 2Cl*
Propegation 1: Cl* + CH4 => HCl + CH3*
Propegation 2: CH3* + Cl2 => CH3Cl + Cl*
Termination 1: Cl* + Cl* => Cl2
Termination 2: CH3* + CH3* => C2H6
Termination 3: CH3*+Cl* => CH3Cl

Sulphates get more soluble as you go down the group, Hydroxides get less soluble as you go down the group. (Group 2)
