Chemical Kinetics Class 12 Important Questions

Chemical kinetics is the branch of chemistry which deals with the speed of chemical reaction, factors affecting the rate and the mechanism by which the reaction proceeds to completion. Chemical kinetics illustrates the connection between mathematics and chemistry. On the basis of rate of reaction, the chemical reactions are classified as very fast reactions, moderate reactions and very slow reactions. Please refer Chemical Kinetics Class 12 Important Questions for more information.

Electrochemistry Class 12 Important Questions

Electrochemistry is the branch of chemistry that deals with the production of electricity from the energy released during spontaneous chemical reaction. Electrochemical changes take place in two types of cells: Electrochemical cell (in this type of cell, chemical energy of a spontaneous redox reaction is converted into electrical energy. These are also known as Voltaic cell or Galvanic cell and Electrolytic cell. Please refer Electrochemistry Class 12 Important Questions for more information.

Solutions Class 12 Important Questions

Concentration terms Solutions are the homogeneous mixtures of two or more than two components. The component that is present in large quantity is called solvent and the one present in small quantity is called solute. Solution can be classified as solid solutions, liquid solutions and gas solutions. Concentration of a solution is the amount of solute dissolved in a known amount of solution. Please refer Solutions Class 12 Important Questions for more information.

The Solid State Class 12 Important Questions

Types of solids and their properties The solids have definite mass, volume and shape. They are rigid and incompressible. Intermolecular distances between constituents of solids are very small. The constituent particles occupy fixed positions and can only oscillate about their mean positions. They are classified in two categories: crystalline solids and amorphous solids. Crystalline solids have a well defined three-dimensional geometrical arrangement of constituent particles. Please refer The Solid State Class 12 Important Questions for more information.

Important Questions for Class 12 Chemistry

Chemistry for Class 12 is a feared subject that requires a lot of memory power and theoretical “mugging up” in order to score marks in the CBSE exams. This general notion brings down the confidence level of many students. But Chemistry should be viewed as a subject which “throws away” marks to its students. Let us learn how to crack this chemistry.
