Disproportionation Disproportionation reactions A disproportionation reaction is a reaction in which the same species is simultaneously oxidised and reduced Example of a disproportion reacti...
Electron Transfer & Change in Oxidation Number Oxidation and reduction in a reaction can be demonstrated in terms of electron transfer For example: 2NH3 + 3Br2 → N2 + 6HBr The oxidation ...
Defining Oxidation Number There are three definitions of oxidation and reduction used in different branches of chemistry Oxidation and reduction can be used to describe any of the following...
Deducing Kc Expressions Equilibrium expression & constant The equilibrium expression links the equilibrium constant, Kc, to the concentrations of reactants and products at equilibrium ta...
Industrial Compromises The Haber Process is, once again, a good example of the need for a compromise of reaction conditions in industrial processes N2 (g) + 3H2 (g) ⇌ 2NH3 (g) The reaction i...
Le Chatelier's Principle Position of the equilibrium The position of the equilibrium refers to the relative amounts of products and reactants in an equilibrium mixture When the position of e...
Dynamic Equilibrium Reversible reaction Some reactions go to completion where the reactants are used up to form the products The reaction stops when all of the reactants are used up In rever...
Catalysts in Industry Catalysts can be divided into two types: Homogeneous catalysts Heterogeneous catalysts Homogeneous means that the catalyst is in the same phase as the reactants ...
Temperature Effects Maxwell-Boltzmann distribution curve A Maxwell-Boltzmann distribution curve is a graph that shows the distribution of energies at a certain temperature In a sample of a g...
