Surface Chemistry Class 12 Notes
Surface Chemistry Class 12 Notes – Chapter 5 The event of attracting and keeping the molecule of a substance on the surface of a solid is called adsorption. This results in an increased concentration on the surface than in the bulk. The expanse of adsorption of a gas on a solid material depends on the …
Chemical Kinetics Class 12 Notes
Chemical Kinetics Class 12 Notes – Chapter 4 Study of chemical reactions concerning the rate of reaction, the formation of intermediates, rearrangement of atoms, and the effect of different variables is called chemical kinetics. Factors affecting rate of reaction are the catalyst concentration of reactants, and temperature. The rate of reaction cannot be predicted but has to …
Electrochemistry Class 12 Notes
Electrochemistry Class 12 Notes – Chapter 3 A device that generates a potential difference between electrodes by chemical reactions is called an electrochemical cell. It comprises two electron conductors which are separated by an ionic conductor and are linked by an electron conductor. The two metallic electrodes are dipped in the electrolytic solution. The important …
Solutions Class 12 Notes
Solutions Class 12 Notes – Chapter 2 A solution comprises of a solute and a solvent. It is defined as a homogeneous mixture of two or more than two substances. They can be classified into three types: Solid solutions Gaseous solutions Liquid solutions Molarity, mole fraction, percentages, and molality are the terms used to express …
The Solid State Class 12 Notes
The Solid State Class 12 Notes – Chapter 1 Solids have definite volume, shape, and mass due to the short distance between the fixed position of particles and strong interactions between them. Amorphous solids behave like super cool liquids as the arrangement of constituent particles has short-range order, isotropic in nature and no sharp melting …
