Webchemical kinetics, the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with thermodynamics , which … WebVideo transcript. - The rate of a chemical reaction is defined as the change in the concentration of a reactant or a product over the change in time, and concentration is in moles per liter, or molar, and time is in seconds. So we express the rate of a chemical reaction in molar per second. Molar per second sounds a lot like meters per second ...
Webhow to find kinetic energy. The kinetic energy of a particle/molecule in a chemical system is, K.E. = (1/2)mv 2, where K.E., stands for the kinetic energy, m, is the mass of … WebChemical kinetics - It is the branch of chemistry which deals with study of the reaction rate in a chemical reaction. It also deals with investigation of reaction mechanisms, the conditions of concentration, temperature, pressure, and catalyst which control the rates of different reactions.
