This course is significant due to its vast applications in industries, biological processes, medicines and research equally. In contents of this course it has been tried to co relate classical theories related to development in advance chemical kinetics. Similarly kinetics of reactions in gaseous form and in solution form varies due to presence of solvent which changes the kinetics of reaction. knowledge of types of reaction and teir mechanism i.e. gaseous reactions, reactions in a solvent, chain reactions etc provides theoretical knowledge required in industrial problrems. In this regard studying this course will enable student to explain mechanism of changes occurring in different applied fields. Kinetics are especially applicable to biology because the infinite number of chemical reactions that happen in biological systems are all in an effort to maintain homeostasis. Basically, kinetics is able to link small applications of chemistry to larger applications in biology and the healthcare field
