rate constant
This term is a technical specification used exclusively within chemical kinetics. It describes the intrinsic speed of a chemical reaction, independent of the concentrations of the reactants, though it is highly sensitive to temperature and the presence of catalysts.
In a laboratory or academic setting, it is distinguished from the reaction rate itself; while the rate changes as reactants are consumed, the rate constant remains fixed for a specific temperature. It is typically denoted by the symbol k in mathematical equations.
Ý nghĩa
Ví dụ
