The introduction to chemical kinetics is the study of rate and mechanism by which one chemical species is converted to another. It is one of the parts of physical chemistry with the most developed mathematical description. Studying basics of chemical kinetics and successful practical application of knowledge obtained demand proficiency in mathematical formalization of certain […]
What is Thermodynamics? Thermodynamics is the branch of science concern with heat energy and its transformation. Thermodynamics deals with the connectivity among heat and work, and the properties of a system in equilibrium. Historically, thermodynamics originated as a result of man’s endeavor to convert heat into work. Thermodynamics was formalized in the nineteenth century by […]
